Abstract

PURPOSE:To stabilize an oscillation output by controlling a variable frequency oscillator on the basis of a phase difference between its oscillation output and a signal obtained by delaying the output. CONSTITUTION:A drawing control signal 10 is added to the output of a frequency discriminator 13 by an adder 11, whose sum output is supplied to a VCO12. The frequency discriminator 13 includes a phase detector 132 inputting the oscillation output of the VCO13 as it is and also inputting the output of the VCO12 delayed through a delay line 131. Consequently, the delay time of the delay line 131 is extended to shorten the intervals of stable points of a negative feedback tape, thereby setting the oscillation frequency of the VCO12 freely at close intervals.
