A rate signal interpreter
Lloyd D. Partridge, Richard Foster Jones · Journal of Applied Physiology · 1965
A simple, on-the-line device is described for converting an electrical pulse pattern into a continuous voltage output proportional to the instantaneous pulse rate. The special purpose circuit and an analog computer version are both given. Pulse rates varying by 30:1 are adequately measured. Multiple ranges are provided. A special feature is that a falling rate is followed as soon as the current interval exceeds the last completed interval. The circuit is stable and components are not critical. impulse rate; rate measurement; instrumentation; interval measurement Submitted on November 16, 1964
