METHOD AND SYSTEM FOR MEASURING THE AMPLITUDE AND PHASE ANGLE OF HARMONICS IN A PERIODIC SIGNAL Abstract of the Disclosure A method and system for simultaneously detecting the amplitude and phase angle of harmonics in a periodic signal. A tunable tracking filter is connected to an input of the system to receive a periodic signal having a frequency within a predictable range. A conditioning circuit is connec- ted to the input to tune the tracking filter to a selected harmonic in the periodic signal. A programmable frequency multiplier forms part of the conditioning circuit and connected for locking the clock frequency of the filter to tune it to the selected harmonic of the periodic signal to provide at its output an output signal having the amplitude and corresponding phase of the selected harmonic.
