Riddle: what is this waveform, and what does it *sound* like? I knew what the answer was going to be, but it surprised me anyway.pic.twitter.com/024W9LWsqh

... unless you also apply a different scale to each 90 degree shifted frequency component (that the Hilbert transform does).
There should be no change to the scales, right? It's only shifting the phases. If you build the sine decomposition of a square wave and just add pi/2 to all the arguments it works.pic.twitter.com/NJElZy4Swq

Hum, you are completely right. I was mixing Hilbert with the derivative (if you derive cos(nt) you get -n sin(nt). But if you apply hilbert transform to cos(nt) you get -sin(nt)). Yeah, my signal processing skills are a bit rust.
Thanks. Twitter will use this to make your timeline better. UndoUndo
