Signal Digitization Three Key Steps | Generated by AI

Question: What are the three stages included in the conversion process of analog signal digitization, which are sampling, quantization, and __?

Answer:

The conversion process of analog signal digitization involves three fundamental steps:

  1. Sampling: This is the process of measuring the amplitude of a continuous-time analog signal at discrete time intervals. The result is a discrete-time signal where the amplitude is still continuous.
  2. Quantization: In this step, the continuous amplitude values obtained from sampling are mapped to a finite set of discrete levels. This introduces a small error known as quantization noise but allows the signal amplitude to be represented digitally.
  3. Encoding: This is the final step where each quantized level is assigned a unique binary code (a sequence of bits). This converts the discrete amplitude values into a digital bitstream that can be processed, stored, or transmitted by digital systems.

Therefore, the missing term is encoding (or coding).
