Claim 2:
3. The method of claim 2, wherein the adjusting the determined times of the group of transitions comprises, for each transition of the group of transitions, performing one selected from the group consisting of:
based on the threshold voltage being a positive voltage, adjusting the determined time of the transition by subtracting an amount of time determined as a function of the positive-going time offset to produce the time of the positive-going zero-crossing of the input AC waveform indicated by that transition; and
based on the threshold voltage being a negative voltage, adjusting the determined time of the transition by adding an amount of time determined as a function of the positive-going time offset to produce the time of the positive-going zero-crossing of the input AC waveform indicated by that transition.
