Heterodyning is a radio signal processing technique invented in 1901 by Canadian inventor-engineer Reginald Fessenden, in which new frequencies are created by combining or mixing two frequencies. Heterodyning is useful for frequency shifting signals into a new frequency range, and is also involved in the processes of modulation and demodulation. T...

A Heterodyne is generated when two frequencies which are close together (and of similar level) interact to give a 'beating' effect i.e. a noise which gets quieter and louder alternatively. An example of this is a twin propeller aeroplane whose engines (running at slightly different speeds) give a throbbing type of noise. See also: Beats.
