  • Abstract
    This article analyses the square demodulation method recommended by IEC on flicker measure and calculate the error brought by this method. On the base of these analyze a new demodulation method is put forward; theoretical derivation and simulation indicate this modified method can reduce measurement error without notable increase of calculation
