Hilbert Transform - Wikipedia, The Free Encyclopedia
In mathematics and in signal processing, the Hilbert transform is a linear operator that takes a function, u(t), III, which inherently exhibits responses of zero magnitude at frequencies 0 and Nyquist, resulting in this case in a bandpass filter shape. A Type IV design ... Read Article
