Harry Nyquist

Harry Nyquist was a pioneering engineer who made important contributions to understanding how signals can be transmitted and processed. His most well-known work established the principle that to accurately reproduce a signal, a system must sample it at least twice as fast as its highest frequency component—known as the Nyquist rate. This concept is vital for digital audio, communication systems, and data transmission, helping prevent errors and ensuring clarity. Nyquist’s work laid the foundation for modern digital communication and signal processing technologies essential to how we transmit and receive information today.
