ABSTRACT:
A digital filter for generating digital output signals from information signals in accordance with a predetermined transfer characteristics includes a coefficient number generator for supplying digital numbers which indicate the values of coefficients which represent the transfer characteristic. The coefficient number generator includes a device for storing increments of successive coefficient values in numerical form and a decoder connected thereto for recovering the coefficient numbers from the numbers stored in the storage device.
