Extracting the Cole-Cole impedance model parameters without direct impedance measurement

A filter-based technique to extract the four parameters that characterise a single-dispersion Cole-Cole impedance model without direct measurement of the impedance real and imaginary parts is reported. Experimental results in the range 100 Hz-5 MHz using apples, apricots and kiwi fruits are given and results are compared with numerical simulations of the acquired model.
