On Determination of Complex Ratio of AC Voltages in a Simultaneously Sampled Two-Channel Data Acquisition System

The article presents the results of measurements of the complex ratio of two sinusoidal voltages (CVR) implemented using PXI system with the National Instrument (NI) PXI 4461 data acquisition module, simultaneously sampling sinusoidal voltages. Results of three reconstruction algorithms were compared and the possibility of minimizing errors related to difference between 4461 module channels was examined.
