Abstract
PURPOSE:To attain stable detection to be immune to a noise or an electric field fluctuation by reproducing a sub-carrier used for the synchronizing detection of RDS(Radio Data System) data from the tertiary higher harmonic of the pilot signal of a stereo. CONSTITUTION:The pilot signal (19kHz) of the stereo included in a composite signal is converted to a short-shaped wave and a tertiary higher harmonic generator 10 is provided to remove the higher harmonic and to amplify it. Then, the RDS data are synchronizing-detected by the output (the signal of 57kHz of a constant amplitude). Further, in order to increase stability, the data are inputted to a phase locked loop PLL to connect a phase comparator 12, an oscillator 13 and a divider 14 in a loop shape and the output is inputted to a synchronizing detector 4. When the output level of the tertiary higher harmonic generator 10 is highly set, the sub-carrier is reproduced to correspond only to the tertiary higher harmonic. Thus, the synchronizing detection to be immune to the noise or the electric field fluctuation can be executed.
