Abstract |
|||
Our final project will be designing and implementing an audio system in which the audio signal is
inputted, wirelessly transmitted, audio filtered and equalized. The audio is inputted through a micro-
phone and is digitized using an Analog-To-Digital converter with the LM4550 AC'97 Codec. The audio
signal is then compressed using the Discrete Cosine Transform (DCT) and is wirelessly transmitted and
received using a low power RF transceiver. The signal, after being decompressed, is then processed using
a Fast Fourier Transform module (FFT) and its Inverse (IFFT), as well as an equalizer module.
