摘要：

An interval-to-frequency converter is described. Design is simplified by use of a varistor, instead of a complicated diode network, to create a hyperbolic capacitor discharge. The capacitor voltage is sampled with a field-effect transistor at the end of the interval between two succeeding spikes in order to give an analog representation of the reciprocal of the interval. © 1968.
