Abstract

PURPOSE: To enable to increase the stability without increasing the loop gain, by providing the phase modulation means performing phase modulation for the input signal.
CONSTITUTION: The output from the sampling hold circuit 5 is fed to the amplifier 11, the amplified output is fed to the first low pass filter 12, and also to the second low pass filter 14 having greater time constant than that of the first low pass filter 12, and the output is fed and amplified at the amplifier 15. The trapezoid wave signal from the trapizoid wave generating circuit 4 is added to the output of the second low pass filter 14 amplified at the synthesizer 16, to modulate the location of the trapezoid wave signal substantially.
