B)8
C)18,000
D)64
E)256

Question

Quizplus · Accepted Answer

Pulse Code Modulation (PCM) typically samples the incoming voice signal 8,000 times per second, which is the standard sampling rate for telephone systems. This allows for the accurate conversion of analog voice data into digital signals for transmission over the phone lines. Choice B, 8, is too low a sampling rate and would result in poor quality audio. Choices C, 18,000, D, 64, and E, 256, are not commonly used sampling rates for PCM in voice data transmission.
