Abstract
Abstract An intermittent operation receiver comprises a receiving circuit 8 receiving one of plural intermittent receiving operation information and data transmitted from a base station and generating its demodulated signal 24, a PLL circuit 7 including a voltage-controlled oscillator 5 and generating two kinds of local signals 25 and 26 different 90° in their phases which are sent to the receiving circuit 8 to process the input signal, and a data processing section 14 which receives the demodulated signal 24 from the receiving circuit 8, decodes the data to generate a first intermittent cycle generation timing signal 18 including a period corresponding to the cycle information of the intermittent receiving operation, and sends this first intermittent cycle generation timing signal 18 to receiving circuit 8 to control the power supply from its power source unit. Meanwhile, data processing section 14 selectively determines a pre-heat time t1, t2 or t3 in accordance with the designated intermittent operating cycle, generates a second intermittent cycle generation timing signal 19 involving the timing of the pre-heat time, and sends this second intermittent cycle generation timing signal 19 to the PLL circuit 7 to control the power supply from its power source unit.
