2 . Amplifiers - Basics

An amplifier can be considered to be any device that uses a small amount of energy to control a larger amount, although the term today usually refers to an electronic amplifier. The relationship of the input to the output of an amplifier — usually expressed as a function of the input frequency — is called the transfer function of the amplifier, and the magnitude of the transfer function is termed the gain. There are numerous types of electronic amplifiers in Chicago depending upon the application.

3 . Window to the Past

Today most sound systems use transistor amplifiers for economic reasons, but valve amplifiers remain popular for guitar amplification, for "high end" hi-fi systems and analog production and replay equipment in recording studios.

4 . Evolution of Amplifiers

One of the first devices to amplify signals was the carbon microphone. By channeling a large electric current through the compressed carbon granules in the microphone, a small sound signal could produce a much larger electric signal. The carbon microphone was extremely important in early telecommunications until other types of amplifiers were available.
