| Abstract: | The principles and features of several typical variable-window impedance algorithms are discussed and a new frequency-response analysis method is developed. The proposed method is available both for phasor-based impedance algorithms and differential equation based algorithms. The proposed frequency-response analysis approach can also be applied to the evaluation of algorithm capabilities against decaying DC offset components. A significant basis for algorithm selection and performance improvements is given in this method. |
