Abstract
Superimposed FM data is demodulated to digital data. A synchronism reproducing circuit (data block detecting section) detects the front of blocks in the digital data to generate a block head signal (a station change timing signal), which is supplied to a control section of a station selecting microcomputer. When a station selecting key requests a change of the received station, station data corresponding to a requested station is supplied to the control section (a station selecting control section). When the block head signal is inputted after requesting the change of the station, the control section begins to output station change data to a PLL frequency synthesizer in order to change the frequency signal in a front end. This prevents a latter part of a block in received superimposed FM data from being NG data.
