Most everyone that has ever purchased an external amplifier is at least familiar with the term voltage gain. Simply, it is the degree to which an amplifier actually ...

at the top of this picture. Each board is two channels. An audio amplifier can boost the small incoming audio signal’s voltage by increasing its voltage, and current. The degree to which the amplifier ...

Normally, if you want to control the gain of an amplifier, you’ll use a variable resistor. You know, like a volume control. But what if you want to control the amplifier’s gain with a voltage?

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 ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

In this article, we will finally answer the one question that has confused musicians for decades: What is the difference between "gain" and "volume" on your guitar amplifier? Although they may ...

This file type includes high-resolution graphics and schematics when applicable. Most data-acquisition systems with wide dynamic range need a method of adjusting the input-signal level to the ...

Boston Acoustics introduces the LCAi220 Local Control Amplifier at the International Consumer Electronics Show. The LCAi220 is an ideal high-performance solution for plasma and other flat-panel TVs, ...

The following is Chapter 21 “Composite Amplifiers” from Linear Technology's Volume II book entitled, “Analog Circuit Design–Immersion in the Black Art of analog design” by Bob Dobkin and the late-Jim ...
