Digital volume control circuit Schematic Power Amplifier and Layout
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.

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.

Stepped Volume Control Circuit Project
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.
Simple Digital Volume Control Circuit Diagram Wiring Diagram
A volume control circuit is a wiring system found in a volume controller. Significantly, adjusting the volume assists in finding the correct volume and balance level for our audio equipment. We will discuss the volume controller circuit, its working, and the step-by-step process of making one.

The automatic gain control circuit AGC provides a signal with less harmonics and additional amplification, between certain limits. As a result, it eliminates those intensity differences, annoying, and of speech music, which sometimes appear on radio and television. Field effect transistors T1 is used as a variable resistance.

All AGC or AVC (Automatic Volume Control) circuits perform two basic funtions; The first of these is to develop a DC (Direct Current) which is proportional to the receiver input signal all the time. The AGC voltage is applied to the RF and IF stage of the receiver where it serves as a Bias voltage.In this way the AGC voltage controls the gain.
