One-Stage Digital Correction of Distorted Dye-Dilution Curves

Abstract

A new method is described for digital correction of the distortion effects on dye-diluted curves imposed by the sampling system. The procedure is based on the convolution theorem, and requires no separate identification of the dynamic characteristics of the measurement system. Following any modification of the sampling system, the method permits the immediate correction of a recorded dilution curve once a new step response recording has been obtained. The fact that no explicit analysis of the transfer characteristics is required presents a significant advantage over correction procedures described earlier.
