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:
- 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.
- 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.
- 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).
