基于matlab对语音信号进行频谱分析，加入高斯噪声，再使用FIR高通、巴特沃斯低通、FIR带通滤波器进行滤波处理(Spectral analysis of the speech signal, adding Gaussian noise, and then use high-pass, low pass, band pass filter for filtering)

matlab面板应用程序，可以进行加减乘除四则运算，各种功能在程序中仅体现(coders introduction of about interface)

FEM1D_SPECTRAL_NUMERIC is a MATLAB program which applies the spectral finite element method to solve the problem u = - pi^2 sin(x) over [-1,+1] with zero boundary conditions, using as basis elements the functions x^n*(x-1)*(x+1), and carrying out the integration numerically using MATLAB s quad() function. This function solves the problem u = - pi^2 * sin( pi * x ) for x in (-1,1), with boundary conditions u(-1) = u(1) = 0.
