Patent number: 8564339Abstract: A method and a system for measuring amplitude and phase difference between two sinusoidal signals, using an adaptive filter. The method generally comprises measuring a sample of an output signal of a system excited by a sample of a reference signal; using an adaptive filter and the sample of the reference signal to determine a and b coefficients that minimize a prediction error on the sample of the output signal, iteratively, and determining the amplitude and/or phase of the output of the system using the a and b coefficients.Type: GrantFiled: August 16, 2012Date of Patent: October 22, 2013Assignee: Soft DB Inc.Inventors: Bruno Paillard, Alex Boudreau
