Abstract
A method includes measuring an impedance of a shunt as a function of frequency and converting the impedance to an admittance in a time domain. The method further includes connecting the shunt in a circuit and measuring voltage data across the shunt over a predetermined interval. The method includes outputting a signal indicative of a current through the shunt derived from the voltage data convolved with the admittance. The method may be implemented in a controller configured to interface with the shunt.
