A PCM system uses a uniform quantizer followed by a 7-bit binary encoder. The bit rate of the system is equal to 50 ´ 106 bits/s.
a. What is the maximum message bandwidth for which the system operates satisfactorily?
b. Determine the output signal-to-(quantization) noise when a full-load sinusoidal modulating wave of frequency 1 MHz is applied to the input.
