WebSo in order to construct the analytic signal we need to find a way of transforming a cosine into a sine. It so happens that the transform for changing cosine’s to sine’s and visa versa is called the Hilbert transform, being: sin cos cos sin … The Hilbert transform is important in signal processing, where it is a component of the analytic representation of a real-valued signal u(t). The Hilbert transform was first introduced by David Hilbert in this setting, to solve a special case of the Riemann–Hilbert problem for analytic functions. See more In mathematics and signal processing, the Hilbert transform is a specific singular integral that takes a function, u(t) of a real variable and produces another function of a real variable H(u)(t).
