The function of this automatic volume control circuit is to amplify signals without distorting its dynamic compression. The amplitude differences in the signal are levelled off and the disturbing ...

To design electronic circuits for audio applications, you need to use components that can handle these ranges of frequency and amplitude, and that can preserve the quality and fidelity of the signal.

This Pre-Amplifier circuit is a minimalistic design, a.o. inspired by valve design, which should help sound clarity. With 5 transistors, it has 0.1% distortion (expected from 60dB loop gain) up to ...

Aiming at the problem of poor human auditory sensation caused by the wide range variation of audio signal amplitude, a high-precision and expandable automatic volume control circuit system is designed ...

The circuit uses three CAT5113P-10 digital potentiometers from Catalyst Semiconductor (see the figure). These pots have control lines connected in parallel as well as isolated resistor elements ...
