ABSTRACT:
In a circuit for determining and storing an average signal value, an overlaid dc voltage part is identified and subtracted from the actual signal. To this end, an all-pass filter with which both a transfer response is optimized and the error is minimized is utilized in a signal processing means in addition to a low-pass filter.
