How do the device EVAL AD5933EBZ is able to calculate the unknown impedance's magnitude and phase using DFT ???

How the real and imaginary parts of DFT are helpful in determining the magnitude and phase of unknown impedance ???

Please explain in detail.

Hi Nikhil,

Have you checked the datasheet already. If not, I'd like to suggest to read it first, since a brief explanation about its theory of operation are being explained in there.
