ABSTRACT:
Systems and techniques for digital processing of FM stereo signals are described. A carrier signal such as a 38 kHz carrier may be recovered and used to process a difference signal such as a left minus right signal. The left minus right signal and a left plus right signal may be used to generate separate left plus right signals.
