Abstract :
A unique broadband technique for suppression of the triple-transit signal in a surface-acoustic-wave delay line is described. The scheme, which utilises two similar delay line channels differing only in the symmetry of the output transducers, suppresses triple-transit signals by a mechanism which is independent of frequency and may be used on low-as well as high-coupling substrates.
