FIGS. 2A and 2B illustrate two example graphical representations of a process similar to method 100 with respect to the passage of time. Graph 200A, for example, illustrates three sinusoidal patterns that represent two example cyclic PWM patterns or cyclic measurement patterns. Pattern 202, for example, represents an oversampling cyclic PWM pattern (or, in the terms of FIG. 1, an “oversampling cyclic control pattern”) and/or a cyclic measurement pattern. The cycles of pattern 202 have been illustrated herein as alternating between a solid line and a dotted line, to ease in understanding. Thus, the first, third, and fifth cycles of pattern 202 are represented by solid lines, and the second, fourth, and sixth cycles of pattern 202 are represented by dotted lines.
Pattern 204, on the other hand, represents a steady-state cyclic PWM pattern (or, in the terms of FIG. 1, a “steady-state cyclic control pattern”). Like pattern 202, the cycles of pattern 204 have been illustrated herein as alternating between a solid line and a dotted line. The sinusoidal nature of these patterns does not necessarily represent any property of the associated PWM patterns or the electricity delivered according to those patterns.
