PURPOSE:To reduce the duty change of an output pulse as compared with the duty change of an input pulse, by applying a signal obtained by giving the inversion and delay to the input pulse to said input pulse. CONSTITUTION:The input pulse of an input terminal INPUT is inverted through a gate X1 to be applied to a resistance R1 and at the same time delayed by a delaying circuit DL and a gate X2 to be fed to a resistance R2. A pulse of about 50% duty emerges as a point C of connection between the resistances R1 and R2 when the duty of the input pulse is 7:5 and the resistance R1 is nearly equal to the resistance R2. This pulse is delivered through an output terminal OUT and via a gate X3. |
