Abstract
In this thesis, the working principle and design steps of the audio amplifier has been investigated. By using the commercial software Multisim, the main modules of the audio amplifiers, including the preamplifier, tone controller and power amplifier have been designed and simulated. Then the experimental circuits have been established on the breadboard and performance testing has been completed. The measurement results show that the theoretical designs are successful and all the technical parameters have satisfied the design requirements.
