The sampling theorem was implied by the work of Harry Nyquist in 1928, in which he showed that up to independent pulse samples could be sent through a system of bandwidth ; but he did not explicitly consider the problem of sampling and reconstruction of continuous signals.
His work laid the foundation for modern information theory and data transmission, the invention of the vestigial sideband transmission system now widely-used in television broadcasting, and the well-known Nyquist diagram for determining the stability of feedback systems.
Na teoria de controle e na teoria da estabilidade, o critério de estabilidade de Nyquist, desenvolvida pelo engenheiro eletricista sueco-americano Harry Nyquist na Bell Telephone Laboratories em 1932 [1], é uma técnica gráfica para determinar a estabilidade de um sistema dinâmico.
