摘要： Provided are methods and apparatus for characterizing a power waveform. Some such methods include sampling the power waveform to generate a plurality of samples and, for each of the samples, recursively processing the sample to generate an aggregate signal energy value, processing the sample to generate a harmonic component signal energy value associated with at least one target harmonic frequency, and accumulating the aggregate signal energy value and the component signal energy value with previously generated aggregate signal energy values and component signal energy values to generate an accumulated aggregate signal energy value and an accumulated harmonic component signal energy value. Methods also include characterizing the power waveform responsive to the accumulated aggregate signal energy value and the accumulated harmonic component signal energy value.
