发明名称 Electronic meter digital phase compensation
摘要 <p>A method compensates for phase differences between sampled values of first and second AC waveforms. The method employs a phase angle compensation factor and sequentially samples a plurality of values of each of the waveforms. For a positive compensation factor, second sampled values are adjusted to correspond with first sampled values by employing, for a corresponding second sampled value, a preceding second sampled value plus the product of: (i) the compensation factor and (ii) the difference between the corresponding second sampled value and the preceding second sampled value. Alternatively, for a negative compensation factor, the second sampled values are adjusted by employing, for the corresponding second sampled value, the preceding second sampled value minus the product of: (i) the sum of one plus the compensation factor and (ii) the difference between the preceding second sampled value and the second sampled value preceding the preceding second sampled value.</p>
