Matlab时频分析

自适应外差滤波器matlab代码：采用调制技术，控制正余弦信号对准干扰的频率，将输入的干扰搬移到的低频进行滤波，滤波处理后的信号再经过一次调制搬移到原来的频率位置，这样我们就得到了合适的干扰复制信号，再将输入信号和干扰复制信号进行差分运算达到抑制干扰的目的(Adaptive heterodyne filter matlab code)

routine to take the Fourier transform of a signal and plot both the time and frequency domain representations. Typical use: >> n = 100 number of data points >> dt = 0.01 spacing between samples >> t = 0:dt:(n-1)*dt time vector >> y = sin(2*pi*10*t) 10 Hz sin wave >> fft_plot(y,dt) plot of signal in time and frequency domain

说明：  实现信号的功率谱估计，AR,MUSIC,FFT,周期图法(Achieve signal power spectrum estimation, AR, MUSIC, FFT, periodogram)

Transfer functions between interfaces can be easily calculated by division of the total (=upward+downward) displacement response on the corresponding interfaces.
