White noise extraction using Matlab and Xilinx ISE: article / Muhammad Izzul 'Afif Ab Hadi

In this paper, a technique to eliminate noise and background noise from .wav signal was discussed. 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 were employed to generate the pure white noise. The results show the performance of the filter and the comparison between the input and output signal. A comparison between Spartan 3E starter board and Xilinx implementation is will made using the same filter and the same input sound signal.
