Abstract
PURPOSE:To prevent a wicker in an output signal from being generated, by inputting the switching signal of a 1/2<n> frequency division signal and a 1/2<n-1> frequency division signal to the set input terminal of a flip-flop. CONSTITUTION:When the switching signal S2 to be inputted to the set input terminal S of a D flip-flop 1 with set input is an L, a clock signal S1 is frequency-divided, and a 1/8 frequency division signal is outputted to the output signal S3 of the clock signal. When the switching signal S2 goes to an H, the output (b) of the D flip-flop 1 goes to the H successively, and the function of a first frequency division circuit is interrupted, and the signal waveform (c) of the Q output of a D flip-flop 3 in a second frequency division circuit becomes a 1/2-frequency divided signal. The signal waveform (e) of the Q output of a D flip-flop 6 in a third frequency division circuit is outputted as a 1/4-frequency divided output signal S3.
