Abstract
A scheme for providing an output signal approximating a true sine wave representative of a sine wave source voltage from corrupted line voltages connecting the source to a load includes the development of a first signal representative of the corrupted lines line voltage. The first signal is then filtered to reject all but higher frequency components and this filtered output is then combined with the first signal to provide a combined signal which is further filtered to provide a final output signal.
