Date :Définition
The process of reproduction of an original modulating signal from a modulated wave, i.e. the inverse of modulation.
A process by which an output wave is obtained having the characteristics of an original modulating wave or signal.
The operation on a previously modulated wave in such a way that it will have substantially the same characteristics as the original.Note :
In English the term "demodulation" has also been used to denote an apparent reduction in the percentage depth of modulation of a received signal due to the presence of a stronger signal of the same or a slightly different frequency.
