INTERDIGITAL TRANSDUCER OF SURFACE SURFACE WAVES AND SURFACE SURFACE WAV FILTERS WITH SYMMETRICAL OR ASYMMETRICAL TRANSMISSION CHARACTERISTICS SUSCEPTIVEL TO BE SIMULATED BETWEEN THE INPUT AND THE OUTPUT

摘要

Surface wave interdigital transducer and filter with predetermined transfer characteristic with respect to symmetry. The transducer (43, 53) is a split-finger transducer in which pairs of split fingers (36) are replaced by a number of single fingers (35).
