Abstract
PURPOSE:To always keep the relation of phase of two outputs constant, by providing an AND gate and a D type FF inputting an output of both FFs and a clock signal, in a phase shifting circuit in which outputs of the two FFs have phase difference of 90 deg.. CONSTITUTION:An input signal (a) is applied to an FF1 and also an FF2 via an inverting circuit 3. The output of the FFs 1 and 2 is changed at the leading of an input clock and a D-FF4 inputs the output of the FFs 1 and 2, an output of an AND gate 5 to which an input clock is inputted and the output of the circuit 3 and is operated at the rise of the clock and resets the FFs 1 and 2. The reset can be made by using a monostable multivibrator in place of the D-FF4. Thus, even if a phase shifting circuit is operated in the phase relation in error at the application of power supply, the reset is made to a desired phase relation at all times, allowing to keep the phase relation of the output at terminals (b) and (c) always constant.
