ABSTRACT:
In a SAW convolver having a multi-layer structure consisting of a piezoelectric layer, insulation layer and semiconductor layer and having at least one combshaped electrode fed with an input signal and a gate electrode for exerting a convolution output, an interface in the form of a jaggedness is formed between the insulation layer and the semiconductor layer to improve the convolution efficiency.
