ABSTRACT:
A lowpass filter with improved D.C. offset characteristics is disclosed. The lowpass filter includes an adjustable amplifier, an offset detecting circuit for producing an offset signal proportional to the D.C. offset between the voltage from the adjustable amplifier and the voltage to the lowpass filter, and a feedback circuit for producing a feedback signal in response to the offset signal which controls the adjustable amplifier to reduce the D.C. offset.
