Abstract
A voltage sweep generator provides a linear sweep voltage signal (triangular wave) between first and second magnitudes in the output circuit of an integrator driven by a control signal. The control signal is produced by a control network responsively to a control signal voltage of fixed magnitude but positive or negative in polarity. The linear sweep voltage signal correlates to reference voltages in a comparator with resultant limits switching signals. These switching signals activate a bistable amplifier to produce the control signal voltage of fixed magnitude and a polarity determinative of ramping up or down voltagewise. The voltage sweep generator is especially useful in a novel dynamic analyzer for evaluation of voltage-current related properties in an external system and, in a particular application, to a unique potentistat employed in performing electrochemical analysis of corrosion phenomena in a test cell.
