HÉTÉRODYNE — Quand deux ondes sinusoïdales de différentes fréquences sont mêlées ou superposées, l’amplitude de l’onde résultante varie avec une fréquence égale à la différence de leurs fréquences respectives. L’hétérodyne est l’appareil qui émet des ondes… … Encyclopédie Universelle
Heterodyne detection — is a method of detecting radiation by non linear mixing with radiation of a reference frequency. It is commonly used in telecommunications and astronomy for detecting and analysing signals.The radiation in question is most commonly either radio… … Wikipedia
