Popis: An electronic differentiator was designed to display directly, in units of mm h~ 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.
