APPARATUS AND METHOD FOR PROCESSING A PILOT SIGNAL

摘要

An apparatus (100) such as a television signal receiver processes a pilot signal to enable, among other things, proper generation of an L-R stereo difference signal. According to an exemplary embodiment, the apparatus (100) includes a signal source (702) operative to provide a pilot signal, and a processing circuit (704-724) operative to process the pilot signal to generate a first processed pilot signal having an AC component and a DC component. The processing circuit (704-724) uses the DC component to control a signal parameter of the AC component and generate a second processed pilot signal that may be used to generate the L-R stereo difference signal.
