Abstract

PURPOSE:To detect the dissidence of a complementary input signal surely, by controlling an oscillating circuit through the output of two rectifying circuits in which the discharge time is set longer than the period of an input signal and complementary input signals with a prescribed period are rectified. CONSTITUTION:Complementary input signals (a), (b) are respectively inputted to input terminals A, B, then a rectifying circuit 1 is charged at level 1 of the signal (a) and a rectifying circuit 2 is charged when the signal (b) is at level 1. Since the discharge time of the circuits 1, 2 is set slightly longer than the period of the signal (a) and (b), when the signals (a), (b) are repetitively inputted in a prescribed period, the rectified output of the circuits 1, 2 keeps the level 1. Thus, oscillating circuits 3, 4 always output the oscillating output in a prescribed frequency and supply it to an oscillation circuit 5. Thus, the oscillation circuit 5 also outputs the oscillation signal in a prescribed frequency, and this is rectified to output a dissidence signal c of level 1. If the signals (a), (b) are coincided at a timing, the signal of level 1 is outputted only to one of the circuits 1, 2, and the dissidence signal C of level 1 from the circuit 5 is stopped.
