Two baseband signals m, (t) and m2(t) are to be transmitted simultaneously over a channel by multiplexing scheme shown below. (a) Sketch signal spectra at points R, S, T. (b) What must be the bandwidth of the channel to handle T without distortion? (c) Design a receiver to recover signals m,(t) and m2(t) back from the modulated 1 signal.
