能够进行信号的HHT变换，使用的是以前的老算法计算的，这个算法虽然老。但是已经证明可用，希望能对初学者有帮助-HHT in signal, using the old algorithm, this algorithm is although old. But has proved available for beginners

基于C的Hilbert变换的源程序，已经证明可以使用。里面有信号数据，可以自行检验。-Hilbert transformation in signal, using the old algorithm, this algorithm is based on programming in C, although the algorithm old. But has proved available for beginners
