ABSTRACT:
A selective call receiving apparatus for receiving FM multiplexed broadcasting signals which is designed to suppress consumed power by efficiently using a battery as a power supply. This apparatus has a reception circuit, an FM multiplex decoder, a subframe counter and a CPU. The reception circuit receives frames having plural pieces of subframes including ID data for a local terminal. The FM multiplex decoder detects a sync signal in each received subframe. The subframe counter counts the number of subframes in accordance with the detected sync signal. The CPU stops the operation of the reception circuit and FM multiplex decoder after causing the subframe counter to self-operate to perform the counting operation based on the sync signal detected in a continuous reception mode, and activates the reception circuit and FM multiplex decoder only when the count value of the subframe counter matches with a previously assigned subframe number and executes data processing including a process of determining if ID data in received data matches with that of the local terminal.
