White noice extraction using matlab and Xilinx ISE / Muhammad Izzul 'Afif Ab Hadi

Background noise is a major problem that disturbed electrical or electromagnetic energy and in environment. This project is aimed to eliminate noise and background noise from .wav signal. White noise is one of the noises that exist in ambient which are consisting of all audible frequency with equal intensity. In this work, waveform audio file format- WAVE, or more commonly known as .Wav is use as a sample and the white noise from the signal was extracted using Butterworth filter. Matlab was employed to generate the pure white noise. The results show the performance of the filter and the comparison between the input and output signal.
