I created the circuit for impedance measurement with using AD5933.

It works very good.

But something isn't clear.

Some words from the Datasheet AD5933.pdf, page 15:

" A DFT is calculated for each frequency point in the sweep. The AD5933 DFT algorithm is presented by formula ... "

Could you explain me please, in detail, how ad5933 gets the real and imaginary parts of the measured admittance at the Frequency Point.

Thank you very much
