Question
Download Solution PDFA 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/sec. What is the maximum message signal bandwidth for which the system operates satisfactorily?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
The bit rate is given by:
r = N × fs
where, r = Bit rate
N = No. of bit
fs = Sampling frequency
The maximum message signal bandwidth is given by:
\(BW={f_s\over 2}\)
Calculation:
Given, r = 50 × 106 bits/sec
N = 7
\(f_s={50\times 10^6\over 7}\)
fs = 7.14 MHz
\(BW={7.14\over 2}\)
BW = 3.57 MHz
