The DA 26S routes a mono program source and priority/page source to as many as six zones. The mono program source is processed by an Automatic Gain Control (AGC) circuit featuring adjustable target level, ratio and attack/decay.
Adafruit Electret Microphone Amplifier - MAX9814 w/ Auto Gain Control. This fancy microphone amplifier module is a step above the rest, with built in automatic gain control. The AGC in the amplifier means that nearby 'loud' sounds will be quieted so they don't overwhelm & 'clip' the amplifier, and even quiet, far-away sounds will be amplified.
Hi friends, www.EVolveElectrics.com A programmable keel offset lets you adjust the offset from the keel at the display. Features:Depth Range: 199 feet Deep and Shallow water alarms Programmable Keel off-set Automatic Gain control Back lighting for maximum night vision.Metric or US standard units Easy to install includes transducer, 20 feet of cable and mounting hardware Fits a standard 2 1 / 16 " gauge mounting hole.
it is often used in circuits where transistor is used as a switch. However, one application of fixed bias is to achieve crude automatic gain control in the transistor by feeding the base resistor from a DC signal derived from the AC output of a later stage.
