ABSTRACT:
A surface acoustic wave convolver comprises a piezoelectric substrate on which a plurality of conductive strip electrodes, an input signal transducer and a reference signal transducer are formed, and a semiconductive substrate on which depletion layer control electrodes and capacitance read-out electrodes are formed. The conductive strip electrodes are connected to the depletion layer control electrodes so that an output signal is taken up from the capacitance read-out electrodes.
