Discrete Transform

A discrete transform is a mathematical technique used to analyze and process digital signals, such as images or sound. It takes a set of discrete data points and converts them into a different representation, often making it easier to analyze patterns, frequencies, or other characteristics. One common type is the Discrete Fourier Transform (DFT), which translates a signal from its original time domain into the frequency domain. This helps in tasks like filtering noise, compressing data, or detecting features. Overall, discrete transforms are essential tools in fields like engineering, computer science, and data analysis.
