Abstract
PURPOSE:To surely select a radio digital system broadcast station quickly by starting frequency sweep so as to receive a broadcast wave and completing the frequency sweep operation when the synchronization with the data signal extracted from the received broadcast wave is detected. CONSTITUTION:If the RDS broadcast reception command takes place in the operation of the radio digital system RDS reception button 24 in the sweep mode, the reception of RDS broadcast is enabled. When the received broadcast wave is a broadcast wave including a radio data, a radio data signal is extracted from the detection output signal of an FM detector 4 via a filter 6. The signal is demodulated by a PLL 7 and the locking is detected (11) via a D-PLL 8. The detection signal turns on the gate 10 and sends the synchronizing detection signal to an AND circuit 17. The signal detected by a signal detector 20 is fed to the circuit 17, a high level sweep stop signal is fed to the controller 14 from the circuit 17 to hold the reception frequency data thereby completing the sweep operation.
