A DC offset measurement and compensation circuit includes a switch arrangement (14) for establishing a zero carrier condition in the circuit. The circuit ouput is integrated (30, 32) to develop any DC offsets, which are converted to analog form (34, 36) and subtracted (18, 20) from the signal output. A reference (REF) may also be subtracted (26, 28) to establish a base digital level for the output.
