Abstract
A corrected method of numerical determination of amplitude- and phase-frequency characteristics of electrochemical systems gotten by discrete electrical signals of impact and response and using Fourier transform is considered. It is proposed to restore first a continuous form of discrete signals using Lagrange polynomial spline before applying Fourier transform.
