Design of an Audio Amplifier
AbstractThe main objective of this project is to design and audio amplifier. Low voltage audiopower amplifier LM386 is used for this purpose. An audio amplifier is designed toamplify frequencies between 100 Hz and 3 kHz. Any amplifier that is designed for thisentire band of frequencies or any band of frequencies contained in the audio range isconsidered to be an audio amplifier. IntroductionAn amplifier is an electronic device that amplifies the voltage, current or power of asignal. Amplifiers are classified in two main ways: The first classification is by functionand other is by frequency response. The functional op-amps are voltage amplifiers andpower amplifiers. In these op-amps output voltage and power gets amplified respectively.Frequency response of an amplifier refers to the band of frequencies that the amplifiercan be designed to amplify. The components of an amplifier respond differently at
