Amplifier
An Amplifier receives a signal from some pickup transducer or other input source and provides a larger version of the signal to some output device or to another amplifier stage.
An input transducer signal is generally small (a few milli volts from a cassette or CD input or a few micro volts from an antenna) and
needs to be amplified sufficiently to operate an output device(speaker or other power handling device).In small signal amplifiers, the main factors are usually amplification linearity and magnitude of gain, since signal voltage and current are small in a small-signal amplifier, the amount of power-handling capacity and power efficiency are of little concern.
