An FDM system has 6 SSB-LC signals (lower side band) with the following information signals bands W1 = Wm2 = W3 = w4 = W5 = W6 =80 rad/sec. Assume that the guard frequency is 5kHz between the adjacent information signals. The FDM signal is modulated again with WBFM having 200kHz peak frequency deviation. Do the following: - a. Suggest suitable sub- carrier frequencies. b. Calculate the transmitted bandwidth. c. Draw the spectrum of the modulated FDM signal if the information signal is sinusoidal. d. Draw a block diagram for the transmitter and the receiver.
