Audio Amplifier - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/computer-science/audio-amplifier
For example, an audio amplifier is a source that provides amplified sound and therefore can be represented at the output terminals of the amplifier by one of the equivalent sources. To be able to view a complicated piece of equipment such as an amplifier simply as a voltage source in series with a resistance aids in the understanding and ...

Amplifiers. The task of an audio amplifier is to take a small signal and make it bigger without making any other changes in it. This is a demanding task, because. a musical sound usually contains several frequencies, all of which must be amplified by the same factor to avoid changing the waveform and hence the quality of the sound. An amplifier ...

A transistor amplifier which raises the power level of the signals that have audio frequency range is known as transistor audio power amplifier. A practical amplifier always consists of a number of stages that amplify a weak signal until sufficient power is available to operate a output device such as loud speaker.

What is an Amplifier? - Definition from WhatIs.com
https://whatis.techtarget.com/definition/amplifier
An amplifier is an electronic device that increases the voltage, current, or power of a signal. Amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds. They can be categorized as either weak-signal amplifiers or …
How does an amplifier work? - Explain that Stuff
https://www.explainthatstuff.com/amplifiers.html
An audio amplifier might work better with some sound frequencies than others; the range of frequencies over which it works satisfactorily is called its bandwidth. Ideally, it has to produce a reasonably flat response or linear response with a wide range of different input signals (so the gain is pretty much constant across a range of frequencies).

An audio amplifier is an electronic device that increases the strength (amplitude) of audio signals that pass through it. An audio amplifier amplifies low-power audio signals to a level which is suitable for driving loudspeakers.
What is an Integrated Amplifier?
https://hub.yamaha.com/audio/gear/what-is-an-integrated-amplifier/
An integrated amplifier is very similar — minus the tuner or other sources. Audio, Integrated. The term “integrated amplifier” refers to the integration of the preamp and power amp, plus phono EQ and tone controls, in a single component. This allows you to save space on your Hi-Fi rack without sacrificing power or capability.
