Explanation by: Mr. Dubey

Pulse Code Modulation (PCM) is a technique used to convert an analog signal into a digital bit stream. It involves three main steps:

  1. Sampling the analog signal
  2. Quantization of the sampled values
  3. Encoding into a digital format (binary)
  • Digital Signal Generator is not related to converting analog to digital.
  • Pulse Signal Modulation is a vague or incorrect term in this context.
  • Hence, the correct and specific term is Pulse Code Modulation (PCM).
