Show Answer

Answer:

Correct Answer: D

Solution:

  • PCM (Pulse Code Modulation) is a sampling technique for digitizing analog signals, especially audio signals. The signals in PCM are binary, that is, there are only two possible states, represented by logic 1 (high) and low 0 (low). Using PCM, it is possible to digitize all forms of analog data, including full motion video, voices, music, telemetry and virtual reality.
