Abstract
An electronic differentiator was designed to display directly, in units of mm h−1, the extension rate of leaves measured with displacement transducers. The differentiator calculates the mean extension rate occurring over predetermined time intervals of 0·25 or 1·0 h and discriminates rates of 0·01 mm hr−1. It reduces considerably the work needed to determine mean extension rates from chart records of transducer output voltage and improves the accuracy of calculated extension rates.This publication has 1 reference indexed in Scilit:
