Definitions

  • the third and fourth HEX numbers (bits 9 to 16) identify the various program groups that are allocated to the federal states.
  • the RDS radio receiver shown in FIG. 2 contains, in a manner known per se, a synthesizer tuner 1, an IF amplifier 2 for selectively amplifying and demodulating the intermediate frequency, a stereo decoder 3 for decoding the stereo multiplex signal and a stereo output stage 4.
  • the reception quality is monitored with the level detector 5 and the multipath detector 6.
  • the level detector 5 takes a measured variable from the IF amplifier 2 in accordance with the IF signal level to determine the signal field strength, while the multipath detector 6 has high-frequency interference amplitudes in the multiplex signal, caused by multipath reception, evaluates.
  • the analog / digital conversion of the control signals for the microprocessor 9 takes place either in the two detectors 5, 6 or in the microprocessor 9, provided that it is provided with corresponding converter inputs.
  • the RDS decoder 7 is also fed with the demodulated multiplex signal. After a 57 kHz bandpass filtering, the quadrature-amplitude-modulated RDS signal is demodulated and the digital data obtained after a subsequent biphase and differential decoding are fed to the microprocessor 9 for further processing.
