The letter deals with the frequency response of a surface-acoustic-wave filter which uses a waveguide between the input and output transducers. The overall frequency response is shown always to be a product of the frequency response of the input and output transducers, even when both of the transducers consist of overlap weighted interdigital electrodes.
