Abstract
PURPOSE: To simplify the constitution of an output signal having at least two types of phases, by constituting a 1/2 frequency divider with a master slave type FF circuit and supplying the output of an FF circuit for slaves and control pulses to a logical circuit.
CONSTITUTION: In a master slave type FF circuit 10, a clock signal CP is divided to 1/2 frequency, and frequency-divided outputs S1, -S1, are obtained from an FF circuit 10M for a master and this is fed to a color encoder 20 as the reference signal. On the other hand, from a slave type FF circuit 10S, frequency-dividing outputs S2, -S2 in which the same frequency-dividing ratio is obtained and the phase only is shifted by 90°, are outputted. In this case, the phase shifting amount changes with the duty of the clock signal CP, and when the duty is 50%, phase lag or lead is made to the signals S1, -S2 by 90 degrees.
