Метод измерения интегральных характеристик сигнала
Аннотация
Предложен новый метод измерения активной мощности и действующего (средне квадратического) значения переменных сигналов в течение интервала времени, вдвое меньшего по сравнению с другими известными методами. Измерение выполняется простым суммированием выборок мгновенной мощности без подстройки времени измерения в соответствии с частотой сигнала. Математическое моделирование позволяет оценить точность предлагаемого алгоритма.
