- 串口采集数据并画图,实时显示数据变化波形-Serial data collection and drawing
LMS--filtering
- 信号在采集和输送过程中往往会参杂着噪声和干扰,将自适应神经网络与信号处理结合起来,采用最小均方(LSM)算法设计的线性自适应滤波器将信号中的杂波成分滤除。用matlab进行仿真,证实线性自适应滤波器具有良好的滤波功能。-Signal acquisition and delivery process often mingled with the noise and interference, the adaptive neural network combined with signal proc

- Matlab小波去噪(默认,强制,给定三种情况) 利用小波分析对监测采集的信号进行去噪处理,恢复原始信号-Matlab wavelet denoising (default, mandatory, given three cases) using wavelet analysis to monitor the signal acquisition denoising treatment, restore the original signal
decomposition
- 运行emd,得到输入信号X的固有模态函数(imf),每列代表着信号X的一阶分量,X就是我们采集的信号。 hhtdn是hht去噪的程序,可以不看,仅看emd 和 findpeaks wvtdn是wavelet去噪程序,如果只是分解信号,仅用下面的语句即可 [C,L] = wavedec(x_noise,dl,wn); x_noise就是我们采集的信号,dl是分解的阶数,wn是分解的母小波名称(% Empiricial Mode Decomposition (Hilbert-Huang
