Design criteria for surface-acoustic-wave convolvers

The effect of acoustic dispersion and attenuation on the performance of surface acoustic wave convolvers is shown to be equivalent to an ideal convolver in cascade with a linear time-invariant filter. Using this result calculations of the implementation loss due to acoustic dispersion and attenuation, transducer bandpass response, and input/output matching networks are given showing the effects of phase and amplitude responses which are representative of typical convolver designs.
