Title Design and Research of of Audio Amplifier
Abstract
This article is mainly for audio amplifier circuit design and debugging according to the working principle of audio amplifier. Audio amplifier design includes three modules, they are pre-amplifier 、 tone control circuit and power amplifier . Each circuit design and simulation based on multisim11.0 software, and achieved the effect of the corresponding amplification module. Set up experimental circuit to test the performance parameters of the circuit on the breadboard. Test results show the audio amplifier design meets the design requirements, All the technical indicators show circuit design is reliable.
Keywords Simulation Tone control circuit Pre-amplifier Power amplifier
