ABSTRACT:
A sampled analog electrical signal in the form of sample currents is processed by combining the input sample current in one sample period with sample currents derived from input sample currents in preceding sample periods. The signal processing is performed by scaling, adding, subtracting and storing sample currents. A circuit arrangement for carrying out the signal processing may be constructed from current mirror circuits and a current memory which is capable of reproducing at its output in one sample period the current applied to its input in a previous sample period.
