Audio Frequency Generator & Response Analyzer

Audio Frequency Generator & Response Analyzer

Abstract

Audio amplifiers have been widely used nowadays to amplify the power output in audio playback devices. A good amplifier will amplify the original sound to a certain greater level and still maintain the quality of the sound that comes out of the speaker. However, a not so good amplifier would interfere with the quality of the sound and thus the output of the speaker will be distorted. The aim of this project is to test the Audio Amplifiers in the audible range of frequencies and test its output response through a Matlab interface which also plots its Amplitude vs Frequency graph (Bode plot). Depending upon the visual analysis of the graph then the user can decide if the amplifier is good to use or not.
