ABSTRACT:
Disclosed is a discrete-time filter configuration employing a shift register having output taps at only preselected stages for developing an output signal that is responsive to the signal of each stage of a shift register. The desired output signal is computed in a filter processing network by multiplying each of the output taps signals by a plurality of filter coefficients, by appropriately delaying the multiplied signals and by summing the delayed signals to produce the desired output signal.
