ABSTRACT:
A transversal filter comprises an acoustic charge transport device comprising an input contact for introducing a signal into a buried channel through which the signal is transported by a high frequency acoustic wave and a plurality of non-destructive sense electrodes overlying the channel for successively sampling the signal. A memory device is provided for storing a plurality of tap weight signals, with each tap weight signal for being associated with one of the electrodes. A multiplier system is operably connected with each of the electrodes and with the storage device for generating the product of the signal sampled at each electrode and the associated tap weight signal. A summer is operably associated with the multiplier for summing the products and thereby generating an output signal.
