Question Paper
1. Choose the correct answer.
An agreed-upon format for transmitting data between two devices is called
modes
prototype
protocol
protopology
In a communication system, noise is most likely to affect the signal
at the transmitter
in the channel
at the destination
in the information source
Amplitude Modulation is used for broadcasting because
it is more noise immune
it requires less transmitting power
its use avoids receiver complexity
it provides necessary bandwidth for high fidelity
Communication in both directions, but one direction at a time, is known as
Half Duplex
Simplex
Full Duplex
Demodulation
In TV transmission, the modulation schemes for Video and Audio are respectively,
FM and AM
F.M and FM
AM and FM
AM and AM
The VSWR of an infinite line is
zero
maximum
infinity
one
A shorted quarter wave and an open half wave acts like a
parallel resonant circuit
series resonant circuit
tuned resonant circuit
either series or parallel resonant circuit
What is modulation and why is it needed?
Draw the block. diagram of an FM receiver and explain its working.
3. Derive an expression of AM wave and also sketch the waveform of an AM wave; then derive the equation for modulation index from it.
Explain the working of a superheterodyne receiver.
What is impedance matching? Explain the various methods of achieving impedance matching.
Describe the working of a radio detector circuit.
Describe various types of losses in transmission lines.
6. Describe the structure, radiation pattern and applications of anyone of the following antennae:
Loop Antenna
Microwave Dish Antenna
What is fading and how does it affect the performance of a communication system?
What do you understand by space wave propagation?
8. Write short notes on any four of the following:
Modulated Transistor Amplifier
Pre-emphasis and De-emphasis
Maximum Deviation Ratio
Virtual Height
Polarization
Antenna Gain
