利用matlab实现数字滤波的一个小实验,程序利用低通滤波器实现将信号.(using Matlab digital filter, a small experimental procedures used to achieve low-pass filter the signal.)

QPSK调制与解调，低通滤波器采用了时域和频域两种实现方式，截止频率fc = 200hz,采样频率fs= 1000hz,欢迎下载参考！(QPSK modulation and demodulation, using a low-pass filter with a time domain and frequency domain implemented way, the cutoff frequency fc = 200hz, the sampling frequency fs = 1000hz.Welcome to download !)

对干涉图进行相位提取后，要获得真实相位图分布，需要对相位主值图进行展开，即相位解缠绕，本程序应用基于调制度方法进行解缠绕。(Right to interfere in the phase diagram extracted to obtain the true distribution of the phase diagram, the need to start phase diagram principal value, that is, the phase winding solution, the program application solution based on the modulation method of winding.)
