Abstract
PURPOSE: To establish the feedback frequency division circuit simple in the circuit constitution, without malfunction even with the input of interference waves, by performing the detection of input signal with phase comparison.
CONSTITUTION: The input signal from the input terminal 1 is inputted to the modulator 4, after the output of the modulator 4 is amplified at the amplifier 5, it is fed to the filter 6 to pick up the required output frequency and it is outputted from the output terminal 8 and multiplied at the multiplier 7 having the number of multiplication n, to constitute the frequency dividing circuit through the feedback it to the modulator 4. Further, the output of the frequency dividing circuit is multiplied at the multiplier 9 having the number of multiplication n+1, inputted to the fixed phase shifter 10, and the phase of the output signal of the fixed phase shifter 10 is compared and detected with the phase of the input signal inputted to the input terminal 1 at the phase detector 11 to output the signal detecting the input level to the output terminal 12.
