When converting analog signals to digital, what process involves discretizing the signal?

The process that involves discretizing an analog signal is sampling. Sampling is the technique used to measure the amplitude of an analog signal at regular intervals. This creates a series of data points that represent the original continuous signal in discrete form, making it suitable for digital processing and analysis. The rate at which the sampling occurs is known as the sampling rate, and it must be high enough to capture the essential characteristics of the analog signal without losing significant information.

Amplification refers to increasing the signal's strength without changing its fundamental nature, while filtering involves removing certain frequencies from a signal. Transmission pertains to the process of sending the signal from one location to another. These processes do not involve the conversion of the continuous analog signal to discrete digital values, which is the essence of sampling.
