信号的hilbert变换,C＋＋代码,不用matlab的可-the c++ code for the hilbert transform

希尔伯特变换测试，使用希尔伯特变换对信号处理，相位偏移90°(The Hilbert transform test uses Hilbert transform to process the signal with a phase shift of 90 degrees)

在matlab中对信号进行希尔伯特变换 边际谱分析。(In MATLAB, the Hilbert transform marginal spectrum analysis is carried out)

产生正弦信号时域波形及频谱，并通过希尔伯特滤波器。其中希尔伯特滤波器有两种产生方式，一是使用MATLAB自带的FDAtool；二是程序编写。(The time-domain waveform and spectrum of sinusoidal signal are generated and passed through Hilbert filter. There are two ways to generate Hilbert filter, one is to use FDAtool in
