在模型阶数和时滞已知与未知情况下，系统辨识与建模的5种最小二乘法。(5 kinds of least square method for system identification and modeling in the model order and time delay are known and unknown.)

用MATLAB实现数字信号处理的程序，包括FIR、IIR设计，以及Z变换、FFT变换(Using MATLAB realize digital signal processing procedures, including FIR, IIR design, as well as the Z transform, FFT transform)

Very fast buck converter model

文件是经典卡尔曼算法matlab实现代码，包括线性卡尔曼滤波，扩展卡尔曼滤波，无迹卡尔曼滤波等，初学者有福啦~~(The code is mainly for kalman alogrithm by matlab,including linear kalman,expanding kalman,unscented kalman.it s very helpful for the green_hand about them.)

1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display 2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data 3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)
