Abstract:
A radio paging receiver comprising:an antenna;a radio frequency (RF) receiver for receiving a radio paging signal through said antenna;a battery for supplying operating power to said RF receiver;a switch coupled between said RF receiver and said battery, for routing said operating power to said RF receiver according to a battery saving signal;an oscillator for providing an oscillating signal having a preset frequency;a delay circuit for delaying said oscillating signal to provide a delayed signal;an exclusive OR (XOR) gate for respectively receiving, through first and second input terminals thereof, said oscillating signal and a second signal derived from said delayed signal and said battery saving signal, and performing an XOR operation thereon to thereby produce a XOR output signal; anda decoder for decoding an output signal of said receiver, and supplying said battery saving signal in accordance with the frequency of said XOR output signal.
