PURPOSE:To ensure the normal holding of the function for the controlled circuit, by forming the control circuit with the output of the dummy circuit and then securing the independent adaptation to the action change of the controlled signal for the control signal. CONSTITUTION:Output terminal TDD of the dummy circuit is connected to terminal TG1, and the timing signal is applied also to terminal TD1 at the time point same as application of the timing signal to terminal TGO. Thus the coincidence is secured at the front edges between the signals of terminals TGO and TD1, and accordingly the perfect coincidence is secured between the time point when the signal of terminal TD1 arrives and that when the output of the basic circuit is fixed. As a result, the output of the basic circuit can be extracted with no delay by applying the signal of terminal TDD to terminal TG1. In this way, the control circuit is formed with the output of the dummy circuit, and the independent adaptation is secured for the control signal to the action change of the controlled signal. Thus the function of the controlled circuit can be kept in the normal way. |
