用Matlab产生正弦波、均匀白噪声、高斯白噪声，并将两种噪声叠加到正弦波上。并给出自相关和功率谱密度波形-Generate sine wave using Matlab, uniform white noise, Gaussian white noise, and two kinds of noise superimposed on the sine wave. And from related to the waveform and power spectral density

基于matlab对脉搏波进行单周期提取，能够很好的提取并且算出单周期波形的平均面积。-Matlab based on single-cycle pulse wave extraction, can be a good area to extract and calculate the average single-cycle waveform.
