Abstract
An electronic volume circuit includes a first signal processing circuit and a second signal processing circuit that are cascaded together. The first signal processing circuit includes a first operational amplifier including an input terminal and an output terminal, one or more input resistors inputting one or more signals to the input terminal of the first operational amplifier, and a feedback resistor connected between the input terminal and the output terminal of the first operational amplifier. The second signal processing circuit includes a second operational amplifier including an input terminal and an output terminal, an input capacitor inputting a signal output from the first operational amplifier to the input terminal of the second operational amplifier, and a resistor and a capacitor connected in parallel between the input terminal and the output terminal of the second operational amplifier.
