Влияние параметров фильтра нижних частот аналого-цифрового преобразователя на погрешность преобразования при обработке медленноменяющихся сигналов в информационно-измерительных системах

Abstract

Исследовано влияние параметров фильтра нижних частот, в том числе частоты среза и порядка фильтра, на входе аналого-цифрового преобразователя на основную погрешность преобразования при обработке медленноменяющихся сигналов. Установлено, что снижение частоты среза фильтра нижних частот снижает уровень аддитивной составляющей погрешности, но при этом в некоторых случаях также снижается стабильность работы системы.

The influence of the low pass filter, including cutoff frequency and the order of the filter, the input analog-to-digital converter for converting the basic error in the processing of slowly varying signals. It has been established that lowering the cutoff frequency of the lowpass filter reduces the error component of the additive, but in some cases also decreases the stability of the system.
