Abstract
PURPOSE:To attain the control of a duty ratio with a simple constitution by outputting a frequency-divided pulse signal having plural different phases with a decoder and inputting two arbitrary outputs to a flip-flop. CONSTITUTION:A pulse signal from an input signal source 1 is inputted to a counter 2 and the output is inputted to a decoder 3. The frequency-divided pulse signal having plural different phases can be obtained from the decoder 3. Two outputs are selected from the output of the decoder 3 through a switch 5, given to a setting input terminal 41 and a resetting input terminal 42 of a flip-flop 4 and thus, the pulse signal of a prescribed duty ratio is obtained.
