A. Give the block diagram of demodulator for each of the following modulated signals: 1- DM 2- PCM 3- SSB-SC B. The message signal 2.cos27.10t is used as an input to PM modulator with carrier freque of 110MHz, carrier amplitude of 4 V, and modulator constant Kp of 1 rad./V. Then; 1- Find the time domain expression for PM signal. 2- Determine the modulation index, frequency deviation, and signal bandwidth. 3- Find the minimum and maximum frequency of the above signal. 4- Is the above PM signal wide or narrow
