フロップ回路とを備えたパルス周期判別回路。A first differentiating circuit that differentiates and outputs the rising edge of the input pulse, a second differentiating circuit that differentiates and outputs the falling edge of the first differentiating circuit, and generates an output that sequentially counts the clock signal and reaches a set value. At the same time, a counter is reset by the output of the second differentiating circuit, and a counter is reset by the output of the counter and is reset by the output of the first differentiating circuit when the output of the counter is not generated, and the determination is made from the set output terminal. A pulse period discrimination circuit comprising a flip-flop circuit that generates a signal.
