摘要: A digital relay and concomitant method comprising employing an analog-to-digital converter, via control logic providing oversampled output of the converter to determine likely values corresponding output, wherein substantially eliminates aliasing resulting from waveform transients in input no anti-aliasing filter is employed input. Also, a Fourier transform converter.
