基于FIR的有噪声语音信号处理 MATLAB处理(Noise based on the FIR of speech signal processing)

说明：  较权威的NS培训文档，希望对大家有所帮助(NS training more authoritative document, we want to help)

波形转换模型建立程序，没有解压密码，可直接使用(waveform conversion process model, not extracting passwords can be used directly)

Ecg codes for ecg delineation.

这个程序关于语音信号的消噪，实现了一个基于递归最小二乘法的自适应噪声抵消器(This program about the speech signal de-noising, implements a recursive least squares based adaptive noise canceller)

多种经典谱估计的方法，直接法谱估计，间接法谱估计，Bartlett谱估计，welch谱估计（含多种窗口的实现）。(A variety of classical spectral estimation method, direct method spectrum estimation, spectral estimates of the indirect method, Bartlett spectrum estimation, Welch spectrum estimation (including a variety of window).)

很好的陷波器例子，其中有实现程序，仿真结果和详细的说明(Examples of good notch filter, which has achieved the program, and detailed description of simulation results)

基带信号周期采样的分析与仿真设计低通信号，对该信号进行周期采样，最后从采样数据中恢复原始信号；改变采样频率，给出相应的仿真结果；考察前端抗混叠滤波器的作用和必要性；分析后端理想恢复滤波器是否唯一。( Periodic sampling of the baseband signal analysis and simulation to design low pass signal, the signal is periodic sampling, finally recover the original signal from the sampled data changing the sampling frequency, gives the corresponding simulation results examine the front of the role of anti-aliasing filter and necessity analysis backend ideal restoration filter is unique.)

active filter is a imrportant in mordern life and power quanlity
