Jan 19, 2010 #1 Sir/Maam, Please, may I ask your help on how to make a automatic sound volume control circuit,from the basic steps,because this is my project study, i'm so worried the.
Digital Volume Control Circuit
Developt the AVC (automatic volume control) voltage - A negative voltage is developed across the volume control R-27 as a result of the rectification of the signal by the diode section (pins 4 &5). Resistor R-28 and capacitor C-28 filter this negative voltage and smooth it out to a DC voltage.

12.04.2009 AGC TL071 TL072 Share this: Tweet Share More 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 effect vanish. With this tehnique, overcompensation in the volume is avoided.

Switching SW1 in the other position the circuit becomes an Automatic Loudness Control and its frequency response varies in respect to the position of the control knob by the amount shown in the table below. C1 boosts the low frequencies and C4 boosts the higher ones. Maximum boost at low frequencies is limited by R2; R5 do the same at high.
Auto Volume Tone Control Circuit Diagram TRONICSpro
Introduction Automatic Gain Control (AGC) circuits Theory and design by Isaac Martinez G. In the early years of radio circuits, fading (defined as slow variations in the amplitude of the received signals) required continuing adjustments in the receiver's gain in order to maintain a relative constant output signal.
Stepped Volume Control Circuit Project
A typical volume control circuit is discussed below. The two-stage amplifier (see the figure below) uses variable resistor R2 as a volume control. Collector load resistor R1 develops transistor Q1 output signal. DC blocking capacitor C1 couples the signal to variable resistor R2 and the transistor Q2 input circuit.

This is the circuit diagram of a digital volume controller for any sort of audio amplifiers or almost any circuit where a mechanical potentiometer is there (conditions apply). Simple and low cost, the heart of the circuit is DS 1669 digital potentiometer IC from Dallas Semiconductors.
Simple Automatic Volume Control with Arduino PCB Isolation
An AVC circuit diagram is usually made up of four main components. First, there's an audio gain amplifier, which amplifies or decreases the input signal. The second component is a filter, which filters out any noise so that only the intended sound is amplified.
