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
