A pcm system uses an uniform quantizer followed by 7 bit binary encoder. The bit rate of the system is equal to 50*106 bits per second. What is the maximum message bandwidth for which the system operates satisfactorily?

Answer:
Maximum Message Bandwidth = 3.57 X 10^6 Hz
Explanation:
Let the message bandwidth be W. Then, sampling the message signal at its Nyquist rate, and using an R-bit code to represent each sample of the message signal, we find that the bit duration is
Tb = Ts/R = 1 / (2WR)
The Bit Rate is Rb = 1/Tb = 2WR
The maximum value of message bandwidth is therefore
Wmax = ( 50 x 10^6 ) / ( 2 x 7 )
= 3.57 x 10^6 Hz
