Abstract: This specification describes a charge-transfer device transversal filter chip in which an input signal is fed in parallel into a number of channels the outputs of which are summed together to provide the desired transversal filter transfer function. Each channel contains an analog shift register, a signal splitter and a polarity selector. The shift registers are of unequal length to provide a different delay thru each channel. The signal splitter provides a plurality of signal paths thru each channel while the polarity selector determines whether a given path in a given channel is added or subtracted in the summation to determine the gain of the given channel in the summation.
