| Abstract: | An interference-protection-optimum method of measuring the frequency of sinusoidal signals using digital filters, based on the root mean square deviation criterion, is investigated. An algorithm for the digital processing of the input signal is proposed, and a model of a digital filter for achieving this and the principle of the construction of a digital measuring instrument for determining the parameters of a sinusoidal signal are proposed.Translated from Izmeritel'naya Tekhnika, No. 8, pp. 60–63, 1994. |
