Q6: Binary channel with bitrate R,=36000 bits/sec is available for PCM voice
transmission. Find appropriate values of the sampling rate fs, the quantizing level
L, and binary digits n assuming fmax= 3.2 KHz.
Ans: 6400 Hz; 32,5 kHz.
Q7: An analog signal is quantized and transmitted by using PCM system. If each
sample at the receiving end of the system must be within +0.5 percent of the
peak -to-peak full-scale value. How many binary digits must each sample contain?
Ans: 7.
