Show transcribed image text Four signals m1(t). m2(t). m3(t). and m4(t) are bandlimited to 3.6 kHz. 1.2 kHz. 1.2 kHz, and 1.2 kHz, respectively. These signals are to be transmitted using TDM.
a) Design a multiplexer that will accommodate all four signals assuming each is quantized to 1024 levels.
b) Determine the frame length of the multiplexer output.
c) Determine the required bandwidth of the transmission channel.
