ABSTRACT:
A surface acoustic wave device comprises first interdigital electrodes for converting an electrical signal into a surface acoustic wave, a medium for propagation of the surface acoustic wave generated by the first interdigital electrodes, and second and third interdigital electrodes which again convert the surface acoustic wave into electrical signals. The second interdigital electrodes, acting as output electrodes for a picture signal, have an electrode aperture length which is larger than that of the third interdigital electrodes acting as output electrodes for a sound signal. The second interdigital electrodes have an electrical capacitance between a pair of electrode fingers in unit length which is larger than that of the third interdigital electrodes.
