Abstract :
An algorithm that uses two integrating voltmeters in a master-slave configuration for accurately estimating the phase shifts between the harmonics of two periodic arbitrary signals is presented. The phase shift between the fundamental components of two periodic arbitrary signals can be measured with an uncertainty of less than 2.5 murad
