  • Eliminating the use of anti-aliasing filters in digital relays by oversampling
    Patent number: 7948420
    Abstract: A digital relay and concomitant method comprising employing an analog-to-digital converter, and via control logic providing oversampled output of the converter to determine likely digital values corresponding to the output, and wherein the control logic substantially eliminates aliasing resulting from waveform transients in input to the converter, and wherein no anti-aliasing filter is employed providing the input. Also, a digital relay and concomitant method comprising employing an analog-to-digital converter, and via control logic providing oversampled output of the converter to determine via Fourier transform likely digital values corresponding to the output, and wherein the control logic substantially eliminates aliasing resulting from waveform transients in input to the converter.
