1) Compare AM and FM modulation (advantages, disadvantages). 2) Why is the use of FM more preferred than PM? Explain your answer. (Hint: Compare the frequency deviations in both cases) 3) Give a short qualitative justification of the fact that FM has more noise immunity than AM.

there is a sinusoidal message signal (f = 100 Hz). Make amplitude modulation with carrier frequency of 10KHz. Use three different modulation depths / indices (0.2 /0.60/0.8). Then demodulate this mixed signal (for these three cases) by try to get message signals. (need matlab codes and graphs)

1. Discuss what will happen to the modulation process of an amplitude modulation (AM) signal if the carrier signal level remains constant and the sideband signal level increases and justify your answer 2. A normal modulation usually has a modulation index ranges from 0 to 1 but in some rare cases, the modulation index can be greater than 1. Discuss what will happen to the output of the receiver if this situation happens.

You are given the task of combining both analog phase modulation(PM) and analog frequency modulation(FM) transmitters . Describe the procedure to combine these transmitters into a single one such a way that your new transmitters operates only in one of the modes (either analog PM or FM) at a time based on the arbitrary choice of transmitter side user and the transmitter side user could change the mode anytime he/she wants during the operation.

2. An AM radio station broadcasts a signal at a carrier frequency ωc, with an amplitude modulation frequency of ωm << ωc, E(t) = E0[1 + A sin(ωmt)] sin(ωct) Show that this is the sum of a wave at the carrier frequency, the lower sideband (ωL = ωc−ωm), and the upper (high) sideband (ωH = ωc + ωm). What total bandwidth is required if the radio station wants to broadcast music that contains modulation frequency components from 20 to 10,000...
