HilbertHRe:

Filter: Extension

Applies the Real part of the Hilbert Transform to an input signal. [1]

Source: Hilbert.sc

Offers the Hilbert transform of an input signal via Weaver's *Second Method*,^{1} known as *Hartley Phasing*.^{2}

The Hilbert Transform, returning the first of two signals in *phase-quadrature*. Considered as a complex *analytic signal*, ^{3} the first may be regarded as the *real* component and the second as the *imaginary*.

[1] this is a composite pseudo UGen. HilbertHRe is built with DelayN. Method *arConv also includes Convolution2 and LocalBuf.
