ABSTRACT:
An acousto-electric convolver having a relatively long effective interaction region for counter-propagating surface acoustic waves and, therefore, a relatively large time-bandwith product implemented by distributing a coupler, such as a multistrip coupler or an array of interdigital transducer taps, over a plurality of parallel-connected single-channel acousto-electric convolvers.
