Abstract:
1. Method for a receiver having a signal path incorporating a tuner, a frequency demodulator circuit for supplying an analog stereo multiplex signal comprising a baseband stereo sum signal, a 19 kHz stereo pilot and a stereo difference signal, which is double sideband amplitude-modulated on a suppressed 38 kHz subcarrier, a sampler for converting the analog stereo multiplex signal into a time discrete digital stereo multiplex signal and a stereo decoder for decoding the time discrete digital stereo multiplex signal into a time-discrete digital stereo sum and a time discrete digital stereo difference signal, wherein the analog stereo multiplex signal is converted into a time discrete digital stereo multiplex signal and then the time discrete digital stereo multiplex signal is shifted over a frequency of 19 kHz to extract at least one of the time-discrete digital stereo sum and the time discrete digital stereo difference signal.
