APPLICATION NOTE 5079

CE31A06 - Harmonic Analysis


Abstract: This application note discusses a compute engine (CE) code that supports the measurement of harmonics present on voltage, current, and power signals. The measurement functions are performed by a tracking bandpass filter, whose center frequency is programmable. A broadband VARh calculation from a digital allpass filter is used to improve the frequency response of VARh measurements. This CE code contains all the other features of the standard CE code described in the Teridian/Maxim 71M6531 data sheet.
