What is AGC on a microphone?
Automatic gain control (AGC) allows a microphone’s signal to automatically adjust to compensate for variations in volume from different talkers, or variations due to a single talker moving relative to the mic.
What is AGC sound settings?
AGC a.k.a Automatic Gain Control is a microphone setting that automatically tracks and adjusts the audio volume of recordings. It takes control away from the user. Many people like this setting as it eliminates several unwanted knobs and buttons from the case of the device.
What is simple AGC?
There are two types of AGC circuits: Simple AGC: The gain control mechanism is active for high as well as low value of carrier voltage. Delayed AGC: AGC bias is not applied to the amplifiers until signal strength crosses a predetermined threshold level, after which AGC bias is applied.
What is AGC and AFC?
The receiver operates in conjunction with the automatic gain control (AGC) and the automatic frequency control (AFC). The AGC improves the dynamic range of the receiver by maintaining a constant signal level at the input of the ADCs. The AFC improves the receiver sensitivity by producing precise baseband demodulation.
