ABSTRACT:
A circuit for supplying weighting voltages to multipliers of a transversal filter comprises a plurality of electronic switches associated with the multipliers for switching magnitudes of the weighting voltages applied to the multipliers, and memory cells associated with the respective electronic switches for storing digital data to turn on or off the corresponding electronic switches. Those memory cells are sequentially addressed by address circuits to store data which define the magnitudes of the weighting voltages applied to the multipliers.
