Re: [linrad] Hilbert transform - looking for code.

Basically what's involved is merely
(1) generating an analytic filter pair by designing a lowpass real FIR and multiplying it point-by-point by a cosine and sine to form a single complex impulse response
(2) filtering the input with the resulting complex FIR filter.
All of the voodoo is in step (1), and that is only low-grade magic :-)

There are also a number of simple IIR designs, but these all suffer from phase non-linearities near the bandedges, and thus aren't suitable for general applications.

I'm looking for some software to perform a Hilbert Transform...
