<p>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.</p> |
