In a certain telemetry system, there are five signals: m1(t), m2(t) and m3(t) are analog signals , but m4(t) and m5(t) are digital. The bandwidth of m1(t) is 900 Hz, m2(t) is 2000 Hz and m3(t) is 1000 Hz. The data rate of m4(t) is 16 kbps and m5(t) is 16 kbps too. The analog signals are to be sampled at rates no less than their respective Nyquist rates, then converted to the PCM format with 4 bits for each sample.
1.Suggest a suitable multiplexing scheme for this purpose.
2.Find the commutators frequencies (in rotations per second)?
3.Find the bit rate in output of the multiplexor?
