We see amplifiers in almost all the electronic equipments around us. It is also found in TV’s, computers, MP3 players and so on. But most of us don't know what is amplifier, what its functionality and how it works? Now will learn about it.
What is Amplifiers?
As we know Amplifier an electronic device that increases the voltage, current, or power of a signal. It is used in wireless communications and broadcasting and also in all kinds of audio equipments.
Types Of Amplifiers:
Amplifiers are categorized into two types weak-signal amplifiers (these are used in wireless receivers and also employed in acoustic pickups, audio tape players, and compact disc players.) and power amplifiers (these are used in wireless transmitters, broadcast transmitters, and hi-fi audio equipment.)
Functionality of Amplifiers:
Amplifiers function is to increase the power the input signal (time varying amplitude or frequency). Amplifiers will take power from the power supply and controlles the output to match the input signal shape with larger amplitude.
