An amplifier is used to increase the amplitude of a signal waveform, without changing other parameters of the waveform such as frequency or wave shape. They are one of the most commonly used circuits in electronics and perform a variety of functions in a great many electronic systems.
Why do we need amplifier electronics?
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. ... Such amplifiers must generate minimal internal noise while increasing the signal voltage by a large factor.
What is the concept of amplification in electronics?
Amplification is the process to increase the magnitude of a signal, generally using an amplifier. Sometimes the amplification can cause a distortion of the signal on the output of the amplifier since there is a very large amplification.
