ABSTRACT:
An SAW (surface acoustic wave) device is disclosed, in which a plurality of SAW delay lines and a plurality of SAW convolver elements are combined; signals delayed by predetermined amounts by the combined SAW delay lines are used as input signals to the SAW convolver elements; and output signals thus obtained from the plurality of SAW convolver elements are added together to be taken out so that apparently a processing time, which is equal to a signal processing time of a single SAW convolver element multiplied by an integer, can be obtained.
