• Define Transponders

Transponder: An automatic device that receives, amplifies, and retransmits a signal on a different frequency (see also broadcast translator).

• what is Moore's Law?

The prediction by Gordon Moore -cofounder of the Intel Corporation that the number of transistors on a microprocessor would double periodically -approximately every 18 months.

• Explain Superhyterodyne reciever.

Superhyterodyne system, the incoming signal is mixed with a local oscillator to produce sum and difference frequency components. The lower frequency difference component called the intermediate frequency (IF), is separated from the other components by fixed tuned amplifier stages set to the intermediate frequency. The tuning of the local oscillator is mechanically ganged to the tuning of the signal circuit or radio frequency (RF) stages so that the difference intermediate frequency is always the same fixed value.

• What are the different types of filters?

low pass, high pass, band pass, band stop, resonant

• What is impulse response?

Impulse response of a system is its output when presented with a very brief input signal, an impulse. A system in the class known as LTI systems (linear, time-invariant systems) is completely characterized by its impulse response. The Laplace transform of the impulse response function is known as the transfer function. It is usually easier to analyze systems using transfer functions as opposed to impulse response functions. The Laplace transform of a system's output may be determined by the multiplication of the transfer function with the input function in the complex plane, also known as the frequency domain. An inverse Laplace transform of this result will yield the output function in the time domain. To determine an output function directly in the time domain requires the convolution of the input function with the impulse response function.

• what are Passive Components?

• PASSIVE COMPONENTS-The components which stores the energy in the form of current or voltage are called as passive components.example:inductors,resistors,capacitors etc"

• Define voltage source

Ideal voltage source is a circuit element where the voltage across it is independent of the current through it. It only exists in mathematical models of circuits. If the voltage across an ideal voltage source can be specified independently of any other variable in a circuit, it is called an independent voltage source.

• Define CMRR

Common-mode rejection ratio (CMRR) of a differential amplifier (or other device) measures the tendency of the device to reject input signals common to both input leads. A high CMRR is important in applications where the signal of interest is represented by a small voltage fluctuation superimposed on a (possibly large) voltage offset, or when relevant information is contained in the voltage difference between two signals.

• Define S/N ratio

Signal-to-noise ratio (often abbreviated SNR or S/N) defined as the ratio of a signal power to the noise power corrupting the signal. In less technical terms, signal-to-noise ratio compares the level of a desired signal (such as music) to the level of background noise. The higher the ratio, the less obtrusive the background noise is.

• Whats BUS

BUS: In computer architecture, a bus is a subsystem that transfers data between computer components inside a computer or between computers. Unlike a point-to-point connection, a bus can logically connect several peripherals over the same set of wires. Each bus defines its set of connectors to physically plug devices, cards or cables together. Early computer buses were literally parallel electrical buses with multiple connections, but the term is now used for any physical arrangement that provides the same logical functionality as a parallel electrical bus.

• what are pull-up registers

Pull-up resistors are resistors used in the design of electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels if external devices are disconnected. Pull-up resistors may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages.

• Where are pull-up regsiters used.

The idea of a pullup resistor is that it weakly "pulls" the voltage of the wire it's connected to towards 5V (or whatever voltage represents a logic "high"). However, the resistor is intentionally weak (high-resistance) enough that, if something else strongly pulls the wire toward 0V, the wire will go to 0V.

• What is the diffrence between a UPS and an inverter?

"The basic difference in layman's terms is: While both provide backup power during mains outage, with the UPS the switch is instantaneous whereas with the Inverter there is a gap of a second or two. This gap is OK for household gadgets such as lights, fans, fridge, etc. but not OK for computers. In technical terms:UPS: The mains power comes to the UPS. The AC is converted to DC and this DC is constantly charging the battery. The output of the battery is fed to the Sine wave inverter and it converts DC to AC and this feeds the equipment. Since power out is always drawn from the battery, there is no time lag when mains swicthes off; it justs stops the battery from being charged and the UPS continues to supply power till the battery runs out. Inverter: The mains power comes to the Inverter. This is directly sent to the output but the AC is also converted to DC and this DC is constantly charging the battery. A sensor and relay mechanism checks whether the mains is ON or OFF. When the main switches OFF, the relay actuator triggers to switch from mains to inverter. Rest is same like the UPS. Because of this sensor and relay, there is a gap between triggering. UPS involves more costly circuitary and is therefor more expensive to make and sell."

• what is fuzzy Logic?

Fuzzy logic is basically about dealing with not only 0 or 1 but also values in between them i.e.floating values

• How many type of resistances are there in a diode

Two, one when forward biased have zero resistance and the other when reverse biased has infinite resistance

· Why a MOSFET is preferred over a transistor?   
A MOSFET is very small in size as compared to a transistor and its biasing is easier as compared to latter.

• Why biasing is required in a transistor?

Biasing is required to get the loadline and the operating point of a transistor.Moreover different regions are achieved through different biasing types.

• How different regions are got and what are those regions?Explain taking a Common Base connection.

Transistor can be biased in 3 different types to get three different regions-Active region,Saturation Region,Cut-off Region

• Explain Active Region- Explain taking a Common Base connection.

Active Region-:Emitter is forward biased and collector is reverse biased

• Cut-off Region- Explain taking a Common Base connection.

Cut-off Region-:Both emitter and collector are reverse biased

• Saturation region:-Explain taking a Common Base connection.

• Why is a common collector called an emitter follower..?

In this configuration the voltage gain is equal to unity and hence a change in base voltage appeears as an equal change across the load at the emitter.Thus the emitter follows the input signal. The most common use of this circuit is to use as a buffer stage which functions as resistance transformation from high to low resistance.

• Define virtual ground

Virtual ground (sometimes called virtual earth) is an important concept found in electronic circuit designs. It identifies a point in a circuit as being held close to the circuit's ground or reference level electric potential. It is called virtual since this point does not have any real electrical connection to ground. The reference may or may not be the same as the local utility ground or earth

• Define real ground

Real ground: Voltage is a differential quantity, which appears between two points. In order to deal only with a voltage (an electrical potential) of a single point, the second point has to be connected to a reference point (ground) having usually zero voltage. This point has to have steady potential, which does not vary when the electrical sources "attack" the ground by "injecting" or "sucking" a current to/from it. Usually, the power supply terminals serve as grounds; when the internal points of compound power sources are accessible, they can also serve as real grounds

• whatis intersymbol interference ans:

In telecommunication, intersymbol interference (ISI) means a form of distortion of a signal that causes the previously transmitted symbols to have an effect on the currently received symbol. This is usually an unwanted phenomenon as the previous symbols have similar effect as noise, thus making the communication less reliable. ISI is usually caused by echoes or non-linear frequency response of the channel. Ways to fight against intersymbol interference include adaptive equalization or error correcting codes (especially soft-decoding with Viterbi algorithm).

• Why crystal is a preferred clock source?

Because of high stability, large Q (Quality Factor) & the frequency that doesn’t drift with aging. Crystal is used as a clock source most of the times.

• What does Quality factor mean?

The Quality factor is also defined, as Q. So it is a number, which reflects the lossness of a circuit. Higher the Q, the lower are the losses.

• What is DTMF

Dual-tone multi-frequency signaling (DTMF) is used for telecommunication signaling over analog telephone lines in the voice-frequency band between telephone handsets and other communications devices and the switching center.

• whats channel coding theorem

Channel coding theorem says "Let a discrete memoryless scource with an alphabet p have entropy H(p) and produce symbols once every Ts seconds. "Let a memoryless channel have capacity C and be used once every Tc seconds. Then if H(p)/Ts <= C/Tc there exists a coding scheme for which the source output can be transmitted over the channel and reconstructed with very small error."

• where is channel coding theorem used

This is basically used for Error Detection.

• What is Biasing?

Biasing is a process of connecting dc voltage to a device by which we can select the operating point of the device. by biasing actually we select the operating point of the device.

• What do you mean by 3 dB cutoff frequency? Why is it 3 dB, not 1 dB?

3db implies 70%(o.7o7) of the power,i'e we r interested to consider the bandwidth range from peak to 70% b'coz uptp 70% its reliable.hence 3db is called as half power freq. 3db value is the mean square value which is 70% of the maximum value.

• What is meant by pre-emphasis

Pre-emphasis -Improving the signal to noise ratio by increasing the magnitude of higher frequency signals with respect to lower frequency signal"

• What is meant by de-emphasis?

De-emphasis-Improving the signal to noise ratio by decreasing the magnitude of higher frequency signals with respect to lower frequency signals"

• What is sampling theorem?

It is defined as the sampling frequency should be greater than or equal to twice the sampling frequency then we can generate the original signal if the condition does not satisfy we get the signal in the distorted mannerit is given as ( fs >/ 2 fs)

• Explian FIR filters

Finite impulse response (FIR) filter is a type of a digital filter. The impulse response, the filter's response to a Kronecker delta input, is 'finite' because it settles to zero in a finite number of sample intervals. This is in contrast to infinite impulse response filters which have internal feedback and may continue to respond indefinitely.

• Quote few examples of FIR Filters

A FIR filter has a number of useful properties which sometimes make it preferable to an infinite impulse response filter. FIR filters: Are inherently stable. This is due to the fact that all the poles are located at the origin and thus are located within the unit circle. Require no feedback. This means that any rounding errors are not compounded by summed iterations. The same relative error occurs in each calculation. They can be designed to be linear phase, which means the phase change is proportional to the frequency.

• What are IIR filters

Infinite impulse response (IIR) is a property of signal processing systems. They have an impulse response function which is non-zero over an infinite length of time. The simplest analog IIR filter is an RC filter made up of a single resistor (R) feeding into a node shared with a single capacitor (C). This filter has an exponential impulse response characterized by an RC time constant.

• what are Asynchronous transmission

Asynchronous transmission uses start and stop bits to signify the beginning bit ASCII character would actually be transmitted using 10 bits e.g.: A "0100 0001" would become "1 0100 0001 0". The extra one (or zero depending on parity bit) at the start and end of the transmission tells the receiver first that a character is coming and secondly that the character has ended. This method of transmission is used when data is sent intermittently as opposed to in a solid stream. In the previous example the start and stop bits are in bold. The start and stop bits must be of opposite polarity. This allows the receiver to recognize when the second packet of information is being sent.

• what are Synchronous transmission

Synchronous transmission uses no start and stop bits but instead synchronizes transmission speeds at both the receiving and sending end of the transmission using clock signals built into each component. A continual stream of data is then sent between the two nodes. Due to there being no start and stop bits the data transfer rate is quicker although more errors will occur, as the clocks will eventually get out of sync, and the receiving device would have the wrong time that had been agreed in protocol (computing) for sending/receiving data, so some bytes could become corrupted (by losing bits). Ways to get around this problem include re-synchronization of the clocks and use of check digits to ensure the byte is correctly interpreted and received.

• How many type of resistances are there in a diode

Two, one when forward biased have zero resistance and the other when reverse biased has infinite resistance

• What is zero crossing rate ?

• Define super conductivity

Superconductivity is a phenomenon occurring in certain materials at extremely low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field. The electrical resistivity of a metallic conductor decreases gradually as the temperature is lowered. However, in ordinary conductors such as copper and silver, impurities and other defects impose a lower limit. Even near absolute zero a real sample of copper shows a non-zero resistance. The resistance of a superconductor, on the other hand, drops abruptly to zero when the material is cooled below its "critical temperature". An electric current flowing in a loop of superconducting wire can persist indefinitely with no power source.

• Decribe Zener Breakdown

In Zener breakdown the electrostatic attraction between the negative electrons and a large positive voltage is so great that it pulls electrons out of their covalent bonds and away from their parent atoms. ie Electrons are transferred from the valence to the conduction band. In this situation the current can still be limited by the limited number of free electrons produced by the applied voltage so it is possible to cause Zener breakdown without damaging the semiconductor.

• Which semiconductor device is used as a voltage regulator and why?

Zener diode in reverse bias is used as voltage regulators. It allows a negligible variation in voltage for a large variation in current

• What do you mean by zener breakdown and avalanche breakdown?

There are two stages that occur as a material begins to breakdown due a large applied voltage. These are zener breakdown and avalanche breakdown

• What do you mean by an ideal voltage source?

An ideal voltage source is a source which allows infinite variataition in current through it without any change in o/p voltage

• Describe avalanche breakdown

Avalanche breakdown occurs when the applied voltage is so large that electrons that are pulled from their covalent bonds are accelerated to great velocities. These electrons collide with the others and knock off more electrons. These electrons are then also accelerated and subsequently collide with other atoms. The current in the semiconductor rapidly increases and the material can quickly be destroyed.

• Does Zener breakdown damages the device.

In the case of Zener breakdown- the current can still be limited by the limited number of free electrons produced by the applied voltage. So it is possible to cause Zener breakdown without damaging the semiconductor

The BODMAS – the precedence of operations also need to be taken care

One possible solution is : 3 * 6/ 2 +1 = 10

Ie, 6/2= 3 mutipley by 3 add one … u get 10

The game can be made hard by including negative numbers, more operations etc

There would be more than one possibility for the question and the scoring will depends upon how many possibilities can be arrived

This can be played in a smaller group.
