するフリツプフロツプとを具備してなることを特
徴とする伝送信号の規定値超過変動判定回路。 A first comparator that detects the presence or absence of voltage fluctuation by inputting a transmission signal to one input terminal and a reference voltage signal to the other input terminal; and an output signal of the first comparator to one input terminal. A second comparator inputs the integrated signal and inputs a reference time level signal to the other input terminal to detect whether the voltage fluctuation time is within a specified time; and an output signal of this second comparator. 1. A circuit for determining a variation in a transmission signal exceeding a specified value, comprising a flip-flop that latches to confirm that a variation in the transmission signal exceeding a specified value has occurred.
