ABSTRACT:
The present invention discloses a frequency stabilizing circuit used for a modulator that modulates an image signal including a synchronous signal into a pulse modulation signal. The frequency stabilizing circuit comprises a detecting device for detecting the synchronous signal included in the image signal that has not been modulated to output a pulse based on the detection, a pulse generating device for outputting a pulse by extracting a modulated signal outputted from the pulse modulator corresponding to the synchronous signal, and a feedback controlling device for increasing and/or decreasing a level of the image signal to be inputted to the pulse modulator in accordance with the difference between the pulse width of the pulse signal outputted from the detecting device and that of the pulse signal outputted from the pulse generating device.
