<P>PROBLEM TO BE SOLVED: To enhance the accuracy of a clock signal by appropriately correcting varied clock signal even if a change in operating environments such as temperature varies the phase of the clock signal outputted from an oscillator. <P>SOLUTION: This clock signal correction circuit corrects a clock signal outputted from the SAW oscillator 2. A standard radio wave is received, a carrier wave signal synchronized with the carrier wave of the received radio wave is generated by a standard radio wave reception part 4, and the phase of the clock signal is corrected by a phase control part 6 so that the generated carrier wave signal is phase-locked with the clock signal. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
