| Abstract: | This paper presents a new method for automatically adjusting the magnitude and the phase error of an alternative signal data acquisition system using the digital filter. A mathematical model for the digital filter implementing automatic magnitude and phase error adjustment is put forward and the design procedure of the digital filter with specific examples is described. Simulation results have proved the validity of the method proposed. |
