4.2-7 Two signals m1(t) and m2(t) both band-limited to 5000 Hz. are to be transmitted simultaneously over a channel by the multiplexing scheme shown. The signal at point b is the multiplexed signal. Which now modulates a carrier of frequency 20,000 Hz. The modulated signal at point c is transmitted over a channel. a. Sketch signal spectra at point a, b and b. What must be the bandwidth of the channel ? c. Design a receiver to recover signals m1(t) and m2(t) from the modulated signal at point c.
