What is the difference between "sampling" and "quantization"?

A) Sampling refers to the discrete representation of amplitude; quantization refers to time intervals.

B) Sampling refers to capturing amplitude values; quantization refers to converting them to discrete levels.

C) Sampling is only applicable to continuous signals; quantization is for digital signals.

D) There is no difference; they are synonymous terms.

Answer: B) Sampling refers to capturing amplitude values; quantization refers to converting them to discrete levels.

Explanation: Sampling involves measuring amplitude values of a continuous signal at discrete time intervals, while quantization converts these amplitude values into discrete levels for digital representation.
