Abstract
PURPOSE: To simplify the circuit constitution, by making the input voltage to the DC voltage in proportional to the input frequency via the monostable multivibrator inverter with trigger pulse conversion.
CONSTITUTION: The input e is converted into the rectangular voltage ez with the rectangular constant voltage circuit consisting of the resistor R1, Zener diodes Z1 and Z2. The voltage ez is differentiated with the differentiation circuit consisting of the capacitor C1 and resistor R2, being the trigger pulse EG rectified with the diode D. This pulse EG triggers the monostable multivibrator M and the voltage E1 having the voltage of a given pulse width T is fed between the terminals 11, 12 of the monostable multivibrator M. The output voltage E1 is in proportional to the input frequency, if the pulse width T and the voltage VCC are constant. Next, the inverter circuit consisting of the resistors R3, R4 and Tr causes the voltage E2 between the terminals 12 and 13, which is zero when the voltage E1 is positive and positive when the voltage E1 is zero.
