H. W: Thirty signals, twenty of them have 4 kHz bandwidth, the other bandwidth of 3 klz are FDM/TDM multiplexed then modulated by a n RF carricr of 800 kHz using AM modulator: 1- Calculate minimum multiplexing and transmission bandwidths. 2- Calculate multiplexing and transmission bandwidths if 0.7 kHz guard band is allowed between each two signals and below the tirst signal.
