1. Describe Modulation Index for AM in detail.
2. Explain Image frequency in detail.
3. What do you understand by FM capture effect?
4. For the FM modulator with peak frequency deviation Δf = 10kHz, modulating signal frequency fm = 10kHz, Vc = 10V and a 500kHz carrier find out bandwidth needed to transmit this signal.
5. Represent the data ‘10110’ using NRZ Unipolar and Polar signaling level.

7. Design the Constellation diagram for QPSK Modulation.
8. Write down the expression for probability of error for BPSK and BFSK schemes.
9. What do you mean by an Entropy?
10. Illustrate that code C = {0000, 0101, 1010, 1111} is a linear Cyclic code.
