Title: Rate signal generator circuit

Abstract: Disclosed herein is circuitry for producing a signal proportional to the rate of recurrence of a periodic input signal applied to the circuitry. When an input pulse is received a timing circuit is energized to charge a capacitor to a predetermined level. The capacitor is then discharged through a resistance circuit having resistance portions which are electronically switched in and out of the circuit so that the discharge, rate of the capacitor defines the desired rate function. Then, upon commencement of a subsequent pulse a sample and hold circuit is actuated to sample the discharge level of the capacitor to provide an accurate indication of the pulse rate.
