Which of the following is NOT an advantage of pulse code modulation?

Which of the following is NOT an advantage of pulse code modulation? Correct Answer No precise clock is necessary for precise reproduction as samples are not reliant on time.

Concept:

Pulse code modulation is a technique to change an analog signal to digital data. A large bandwidth is required in PCM system.

Explanation:

A PCM encode contain three components:

1) The analog signal is sampled

2) The sampled signal is quantized

3) The quantized values are encoded as stream of bits

As samples are dependent on time, an accurate clock is required for accurate reproduction. If either the encoding or decoding clock is not stable, these imperfections will directly affect the output quality
