ABSTRACT:
The invention relates to a device which forms the product of convolution of two signals available in electrical form. This device consists of a substrate of lead molybdate in which there are created, at the two ends, volume elastic waves, which are longitudinal and transverse respectively for each of the two applied signals. The non-linear interaction of these waves produces an elastic wave of transverse mode, representing the product of convolution of the two signals.
