摘要：
A first periodic voltage waveform (20) is downconverted into a second periodic voltage waveform (35, 36). A plurality of temporally distinct samples (SA1, SA2, . . . ) respectively indicative of areas under corresponding fractional cycles of the first voltage waveform are obtained. The samples are obtained in response to a control signal indicative of a code used to produce the first voltage waveform, and the samples are combined to produce the second voltage waveform.
