Abstract
A convolver includes first and second buried channels, with each of the channels comprised of a piezoelectric semiconductor. The input of one channel is associated with the output of the other channel. An acoustic transducer is positioned adjacent each input for generating an acoustic wave which propagates through the associated channels and thereby transports charge from the input to the output thereof. A non-destructive sensing array overlies the channels and samples the charge transported thereunder. The array includes an assembly for summing the sampled charge and for generating a product. An electrode is operably associated with the summing assembly for integrating the products and generating a convolution signal.
