ABSTRACT:
An adaptive digital filter is supplied with an alternating current noise signal by a separate reference line. The filter samples input signals and the signal on the reference line several times during each cycle of the noise signal. The samples of each of the input signals are then summed and optionally averaged for one cycle of the noise signal to produce filtered signals. The sampling interval for the input and reference signals is adjusted so that the sum of the reference signal samples for one cycle of the noise signal approaches zero.
