摘要： Plural variable gain amplifiers amplify audio signals of plural channels for each channel. An interface receives, from outside, plural gain control data individually designating gain of each channel. Plural gain controllers respectively switch the gain of the plural variable gain amplifiers, based on the plural gain control data. The plural gain controllers arrange timing to change gain of a variable gain amplifier corresponding to gain control data received in a predetermined data entry period, among the plural gain control data that are inputted at different timing.

摘要： A first amplifier amplifies a first audio signal. A synthesizer circuit synthesizes an output signal of the first amplifier with a second audio signal. The first amplifier is arranged such that a first state in which the first amplifier amplifies a signal with a set gain and a second state in which the first amplifier outputs a fixed bias voltage can be seamlessly switched. A signal processing unit is disposed upstream of the first amplifier, subjects a third audio signal to a predetermined signal process, and outputs it as the first audio signal. When a state of the signal processing unit is switched, the first amplifier is changed from the first state to the second state, the state of the signal processing unit is switched in the second state, and subsequently the first amplifier is switched from the second state to the first state.

摘要： In an electronic volume apparatus, a gain having an initial value g1 at time t=0 in an initial state is transited to a target value g2 at time t=Tp after a certain transition period Tp elapses. A gain control unit controls the gain of the amplifier depending on a control function g(t) which satisfies the following conditions (1) to (3): g(0)=g1, g(Tp)=g2; (1) g′(Tp/2)>g′(0); and (2) g′(Tp/2)>g′(Tp). (3) where g′(t) is time differentiation of g(t).

摘要： A first selector receives a second input signal and a second reference voltage, and selects either one. A first buffer receives the output signal of the first selector, and outputs the signal thus received to a terminal of the first resistor, and to a terminal of the third resistor. A second selector receives a first input signal and a third input signal, and selects either one. A fourth selector receives, as input signals, the output signal of an operational amplifier, a signal that corresponds to the output signal of the second selector, and a signal that corresponds to the second input signal, and selects one signal selected from among the signals thus received.
