Abstract

With the advent of the information age, signal transmission has been involving many kinds of fields. During the process of voice signal transmission, there would be inevitably doped with some noise signal, but which would not happen if the very designed filter has been used. In this paper, the window function method is used to select the fast Fourier transform interval, so as to design a FIR digital low-pass filter to achieve the doping in the speech signal in the random noise elimination, and analyze the time domain and frequency domain characteristics of voice signal before and after denoising, compare the quality difference of voice signal before and after filtering. This paper aims to verify the validity of the designed FIR digital low-pass filter's function by Matlab simulation.
