ABSTRACT:
A battery saving circuit for use in a portable radio communication apparatus adapted to receive a communication signal which includes a preamble and identification codes. The apparatus includes a receiver section, a waveform shaper section, a decoder section and a power supply. The battery saving circuit, forming a portion of the decoder section, periodically generates a first control signal which causes the power supply to be electrically connected to the receiver and waveform shaper sections. A second control signal is generated to disconnect the receiver and waveform shaper sections from the power supply when, during an assigned time period, the preamble code is not detected. A third control signal is generated to maintain electrical connection between the power supply and the receiver and waveform shaper sections for a selected period of time after the preamble is detected.
