Abstract
The present invention relates to surface elastic wave memory correlators, which make it possible to form the correlation product of two successive signals. It consists in sampling the first of said signals at the surface of a surface elastic wave delay line, in storing the samples in capacitors and in forming the product of said samples with said second signal, by varying the impedance of the circuits through which said second signal passes, as a function of the value of the stored samples. The products obtained are added in order to give the correlation signal.
