So, the hilbert transform of a sin wave IS an inverted cos wave
Thanks!

It is on the first page of the document I gave you a link to.

Please can someone just tell me what the hilbert transform of a sine wave
is?

But Al, a Hilbert transform shifts phase 90 degrees. Depending on
implementation, it can be either way. Maxboard wants to know which way.

I would hope that is the case. If they were the same, a Hilbert
transform would be rather a waste of time, wouldn't it? :-\

No.
sin(wt) is not the same as -cos(wt).

The Hilbert transform of a sine wave is an inverted cos wave, right?
