Implementation of hardware-software filtering in a measuring converter of the arterial pulse signal

Full Text

Abstract

The paper deals with a technique of hardware-software filtering implemented in a measuring converter of the arterial pulse signal. As a result of research the optimal pass band of a digital filter and optimal cut-off frequency of a hardware high-pass filter were determined. The metrological characteristics of a photometric measuring converter of the arterial pulse signal were investigated. The instrumental errors of measurement of amplitude-time characteristics of the recorded arterial pulse signal were determined.
