Introduction
Maxim is introducing a new compute engine (CE) code that supports measuring harmonics present on the voltage,
current, and the power signals to use for analysis. The measurement functions are performed by a tracking band-
pass filter whose center frequency is programmable. A broadband VARh calculation using a digital all-pass filter is
utilized in this CE code to improve the frequency ……
