While I have figured out how to perform and apply calibration, I am still fumbling with a simple problem.
The problem is, when applying calibration, I need to use complex numbers, meaning I build tables of these, indexed by frequency.
But as the measurement frequency is likely to be between 2 frequencies in the lookup table, interpolation is needed.
Is there an easy standard way to interpolate between 2 complex numbers? (just linear interpolation, no fancy spline needed)
Must be a somewhat common problem, but quick google just seem to suggest everyone use matcad
I'm sure there is a simple way of doing it, and I'll figure it out eventually, but any hints much appreciated.
