The 'quadrature component' of any waveform can be found by
applying a Hilbert transform. Which in this context means
just a FIR filter. It will have some delay, but if the
only purpose is measurement that's no problem.

This is utter nonsense. You could as well claim that the 
earth is flat disk and ignore all evidence that it isn't.
If you want to contribute anything useful, please stop
spreading this sort of manifest lies.
