音除去回路。 Diodes connected in antiparallel to each other are connected to the emitter of the signal input emitter follower, into which a signal containing a noise component is inputted as a base, and a predetermined diode is connected to the output side of these diodes and the cathode side of one of the diodes whose cathode is the input side. A level bias value is set, and the anode side of the other diode whose input side is an anode is connected to the emitter of a bias adjustment emitter follower that can be adjusted to an arbitrary level bias value. circuit.
