旧することを特徴とする基線復帰回路。[Scope of claim for utility model registration] A DC blocking capacitor is connected between the input and output terminals,
In a signal circuit in which a reference potential is connected to the output terminal via a reference potential setting resistor, the reference potential and the signal circuit voltage are compared, and a positive or negative potential is supplied depending on the magnitude relationship between these two voltages. Comparison control means for controlling the switching means is provided, and the switching means operates when a magnitude relationship occurs between the reference potential and the signal circuit voltage to connect the output side electrode of the capacitor to the positive or negative potential supply means. A baseline return circuit characterized in that the circuit is connected to the base line and recovers when the two voltages become equal.
