Abstract (en)

[origin: EP1239616A2] The method involves processing a sampled stereo multiplex signal (MPX) in two branches, computing an error signal describing the phase angle between the RDS signal carrier and the output signal of an oscillator (OZ) from the high pass filtered signals of the first and second branches and the RDS bit clock (CL) and generating a correction signal for the oscillator from the error signal after filtering. Independent claims are also included for the following: a circuit for demodulation of radio data system or RDS signal.
