Zusammenfassung:We have studied on a new type surface acoustic wave convolver consisting of multi channel waveguide, namely, in which the drawbacks inherent to an acoustoelectric convolver, and also to an elastic convolver are eliminated. We have adopted focussed interdigital transducers as the input to the new convolver, and improved its frequency characteristics and the time bandwidth product.
