Question

part 1) Sketch the spectrum at point (a) and (b) of the receiver.
part 2) What must the bandwidth of the channel be required for the system?
part 3) Design a transmitter to multiplex the signal m1(t) and m2(t) for the receiver

Two signals, mi(1) and m₂(1) (both band-limited to 10,000 Hz) are to be transmitted simultaneously over a
channel using a custom frequency division multiplexing scheme. The multiplexing system is shown as below,
