Long ago, single-sideband transmitters used a filtering technique or a phasing methodology. The phasing exciters essentially were quadrature phase splitters -- and yep, the Hilbert transform was the mathematics behind this. (another method, by Weaver, uses two Hilbert transforms.
Really good stuff here -- and many thanks!

- electroagenda 3y agoYes. I intend to write one more article on single side band, and another one on the analytic signal. Including there the details you mention. But for this one I just wanted to focus on Hilbert Transform and a little bit on the applications. Otherwise it would have been a bit "hard" for many readers. Thanks for your feedback!
