Gibbs, D.

Gibbs, D. refers to the Gibbs phenomenon in the context of signal processing and mathematics. It describes the overshoot (or oscillation) that occurs when a signal composed of a finite number of sine waves approximates a step function. When you try to create a sharp transition in a signal (like switching from low to high), the approximation can overshoot the desired value. This phenomenon highlights the challenges in accurately representing sudden changes using smooth functions and is important in areas like audio processing, image reconstruction, and Fourier analysis.
