A switch turns an electric machine off or on. An amplifier makes an electric machine louder. Amplifiers are used to make music louder when Guitars are hooked up to them.

An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
A transistor is an electronic component. By itself it has little use. An amplifier is a complete, functional circuit, generally made up of several components. A transistor can be a component part of an amplifier, however an amplifier may be constructed without any transistors (using vacuum tubes instead, for instance).

• High Input Impedance Amplifier. • Low-Noise Amplifier. • Differential Amplifier. • Constant Current Source. • Analog Switch or Gate. • Voltage Controlled Resistor. • JFET as a Switch • JFET as a Chopper • JFET as a Current source • JFET as a Amplifier • JFET as a Buffer
normal amplifier is a mathametical operation analog the computer, magnetic amplifier is sound operation of the signal
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.

A doped fiber amplifier amplifies light in the fiber as a LASER.A semiconductor amplifier is an electronic circuit that amplifies electrical signals.
1.Small signal amplifier can be designed easily using s parameter while large signal amplifier not.
Difference between Amplifier and Repeater 1. Amplifier is used to magnify a signal, whereas repeater is used to receive and retransmit a signal with a power gain. 2. Repeater has an amplifier as a part of it. 3. Sometimes, amplifiers introduce some noise to the signal, whereas repeaters contain noise eliminating parts.

single stage amplifier contain only one stage transistor amplifier but multi stage contain more than one amplifier stage
