—In this paper we propose a fractional lowpass transfer function of the order (n + α) where n is an integer and 0 < α < 1. We show how this filter can be designed using an integer-order transfer function approximation of the fractional-order Laplacian operator s α. A 1 st order lowpass filter with fractional steps from 0.1 to 0.9, that is of order 1.1 to(More)
In the field of bioimpedance measurements, the Cole impedance model is widely used for characterizing biological tissues and biochemical materials. In this work, a nonlinear least squares fitting is applied to extract the double-dispersion Cole impedance parameters from simulated magnitude response datasets without requiring the direct impedance data or(More)
