An FDM is used to multiplex two groups of signals using AM-SSB, the first group contains25 speech signals, each has maximum frequency of 4 kHz, the second group contains 15 musicsignals, each has maximum frequency of 10 kHz. A guard bandwidth of 500 Hz is used betweeneach two signals and before the first one.1. Find the BWmultiplexing2. Find the BWtransmission if the multiplexing signal is modulated using AM-DSB-LC.
