Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain the electronic amplifier, relay its function, key measures and types from electronics sources, and distinguish it from passive devices and from other signal-processing circuits.

An electronic device that increases the power, voltage or current of a signal, taking a weak input and producing a stronger output using energy from a power supply; amplifiers are basic building blocks of audio, radio, instrumentation and communication systems. The registry aliases name integrated-circuit families and parts used to build amplifiers. Amplifiers are characterised by gain, bandwidth and distortion, and different classes trade efficiency against fidelity.

What it is for: Increasing the strength of an electronic signal.

It can be explain the function; relay key measures such as gain; relay amplifier types; distinguish it from passive devices.

Distinguishing features

Increases signal strength

Uses external power

Characterised by gain

Building block of systems

What it looks like

Not a single appearance; a circuit or chip, from a small integrated circuit to a large audio unit.

How it is recognised

A device that strengthens a signal using external power
