Abstract

Abstract Impedance measurements on a new, model RC electrical circuit have been conducted with the use of a continuous frequency scanning method. The impedance of the model circuit was determined for different types and sizes of the analyzing window. The values of the resistance and capacitance parameters obtained for different analyzing windows were compared with their true values. The influence of the type and length of analyzing window on the accuracy of the results has been recognized.
