Pulse code modulation PCM is used to digitize a voice with 8
Pulse code modulation (PCM) is used to digitize a voice with 8 bits of sampling for transmission on a DS0 line. What is the max rate of encoding for one of these voice channels?
A. 28.8Kbps
B. 56Kbps
C. 64Kbps
D. 128Kbps
Solution
C. Pulse code modulation (PCM) is used to digitize voice with 8 bits of sampling 8,000 times per second, which yields 64Kbps for one DS0 channel. Answers A, B, and D are incorrect because 28.8Kbps, 56Kbps, and 128Kbps are not the rates of transmission for one DS0 channel
