Voltage Controlled Amplifier — Dans le cadre de l audio, le VCA (voltage controlled amplifier, ou amplificateur commandé par tension) est un système de groupage de commande dans une console de mixage. Il permet de commander par un fader unique un ensemble de signaux qui,… … Wikipédia en Français
Amplifier — For other uses, see Amplifier (disambiguation). Generally, an amplifier or simply amp, is a device for increasing the power of a signal. In popular use, the term usually describes an electronic amplifier, in which the input signal is usually a… … Wikipedia
Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… … Wikipedia
Variable-gain amplifier — A variable gain or voltage controlled amplifier is an electronic amplifier that varies its gain depending on a control voltage (often abbreviated CV). VCAs have many applications, including audio level compression, synthesizers and amplitude… … Wikipedia
Variable Gain Adjustment — Ein Variable Gain Adjustment, oder Variable Gain Attenuator (auch „Step attenuator“ genannt), kurz VGA, ist ein elektronisch verstellbares Dämpfungsglied in einem HF Pfad. Die Dämpfung kann sowohl binär als auch analog (über eine Steuerspannung)… … Deutsch Wikipedia
Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… … Wikipedia
Negative feedback amplifier — Figure 1: Ideal negative feedback model A negative feedback amplifier (or more commonly simply a feedback amplifier) is an amplifier which combines a fraction of the output with the input so that a negative feedback opposes the original signal.… … Wikipedia
Current-feedback operational amplifier — Representative schematic of a current feedback op amp or amplifier. The current feedback operational amplifier otherwise known as CfoA or CfA is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage… … Wikipedia
Valve RF amplifier — A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical , typically (but not exclusively) radio frequency signals.Low to medium power valve amplifiers for frequencies below… … Wikipedia
Operational amplifier applications — This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Contents 1… … Wikipedia
Operational transconductance amplifier — Schematic symbol for the OTA. Like the standard operational amplifier, it has both inverting (−) and noninverting (+) inputs; power supply lines (V+ and V−); and a single output. Unlike the traditional op amp, it has two additional biasing inputs … Wikipedia
