調信号発振器。 The clock pulses sent out from the oscillation block are received by two ripple counters, the periods between the ripple counters and the outputs are shifted, and the pulse signals with two different periods are input to the S-R flip-flop circuit to change the periods of the two waves. A pulse width modulation signal oscillator characterized in that a digital signal is formed in response to a difference.
