whose discrete taps could be subjected to arbitrary amplitude and phase weighting and then summed. manner arbitrary impulse responses could be synthesized leading to a universal filte I. .s.:lementation. Although fixed amplitude weighting of taps is rather simply obtained in surface acoustic wave 'liters, nondispersive phase weighting is very difficult. adaptive transversal filter may be composed of a number of fixed orthonormally coded tapped delay lines. It is shown that by changing the amplitude drive to each tapped line input transducer the effect of arbitrary amplitude and phase weighting may be obtained. frequency filters. coded surface wave delay lines. The original paper by Kallman described a transversal filter composed of a tapped delay line
