使用matlab的小波分解和重建函数对24位的ADC采样数据进行小波变换和去噪，去噪使用阈值算法，阈值的选取具体使用了6种方法进行对比，对于不同信号其效果是不同的！把去噪后的信号和原始信号放在一个图中，使用不同颜色的曲线进行对比，效果可以很直观的表现。(Using matlab wavelet decomposition and reconstruction of the function for 24-bit ADC sampling data wavelet transform and denoising, denoising using the threshold algorithm, the threshold selecting specific methods used six kinds of contrast, the effect for different signals is different The! After the denoising signal and the original signal on a map using different colors to compare curves, the effect can be very intuitive performance.)

Periodogram-powe
说明： 平均周期图法和平滑平均周期图法估计功率谱
从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!!
用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz，时间序列长度2048，FFT数据点数2048。其中welch法使用hanning窗，窗口长度600．(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)
