Variable gain amplifiers often use a mechanical potentiometer to set the gain. An example is a volume control dial. However, when the analog signal path is digitally controlled, a digital ...

AGC (automatic gain control) amplifiers are frequently used devices. Their gain is a function of the level of their input signal. The main function of AGC amplifiers is compression of a signal, but ...

[Alan’s] friend came to him with a problem. He loved listening to his scanner, but hated the volume differences between stations. Some transmitters would be very low volume, others would nearly blow ...

What are VGAs? Variable gain amplifiers (VGAs) are signal-conditioning amplifiers with electronically settable voltage gain. There are analog VGAs and digital VGAs, or DVGAs. An analog voltage ...

In the process of creating various products that deal with analog signals, one frequently requested function is automatic gain control. This feature is needed to control the amplitude of a given input ...

The "Audimax II RZ" is an automatic gain control amplifier produced by the Columbia Broadcasting System in the U.S.A. It is intended to reduce the need for manual control of signal levels at a studio ...

A component of most GPS receiver front-ends, the automatic gain control (AGC) can flag potential jamming and spoofing attacks. The detection method is simple to implement and accessible to most GPS ...
