ミューティング信号作成用トリガ回路。In an audio device having a switch that performs switching to generate a polarity change between positive and negative, the circuit includes a circuit that generates a negative trigger pulse when a switching signal generated by switching the switch changes from a positive side to a negative side; The circuit includes an operational amplifier and a circuit that generates a positive trigger pulse when a switching signal changes from a negative side to a positive side, and the negative trigger pulse is applied to a non-inverting input terminal of the operational amplifier to generate an output signal. 1. A trigger circuit for creating a muting signal, wherein the trigger pulse is temporarily inverted, and the positive trigger pulse is applied to an inverting terminal of the operational amplifier so that the output signal is temporarily inverted.
