ELECTRO MECHANICAL INTEGRATOR

摘要

ELECTRO-MECHANICAL INTEGRATOR An electronic integrator for integrating a linear voltage signal utilizes a Voltage-To-Frequency converter for converting the voltage to input frequency. A binary counter counts pulses of the input frequency. The binary counter generates a first operating frequency which is applied to a scaling circuit and another calibration frequency which has a much higher rate than the operating frequency. Both, however are proportional to the input frequency. The scaling circuit scales the operating frequency to a selected extent to form a counting signal. Using the double pole switch, either the calibration frequency or the counting frequency are applied to a pulse counter which is either used to integrate the input voltage signal by counting up pulses of the scaled counting signal, or the integrator can be calibrated using the calibration frequency which quickly increments the pulse counter.
