Sampling Function

A sampling function is a process used to convert a continuous signal (like sound or light that varies smoothly over time) into a series of discrete data points. Imagine taking snapshots of a moving scene at regular intervals; these snapshots capture the essential information about the original signal. The sampling function determines how often and how accurately these snapshots are taken. Higher sampling rates mean more snapshots, preserving more detail. This process is fundamental in digital signal processing, such as converting audio into digital files, enabling computers to store, analyze, and reproduce analog signals accurately.
