Re: Complex in/Complex out Hilbert?

[Frank Brickle]

Perhaps I'm misunderstanding what you're saying, but isn't the received signal already analytic? The goal is to step it down to real baseband. You don't need a Hilbert transform going in that direction.

So, to demodulate, you'd just spin the signal to baseband, filter, and throw away the imaginary part of the result. Voilá, real demodulated signal.

I noticed that the version of GnuRadio that is released in Ubuntu 20.04
has a real-in/Complex out Hilbert block, which is great for modulating
SSB. But it lacks a complex-in/complex-out Hilbert for doing the
demodulation side. Is there any package with the complex/complex form of
the Hilbert? Or has anybody given thought to having an option in the
Hilbert module for doing complex in?
