Abstract
PURPOSE: To enable simple circuit constitution, by triggering monostable multivibrator through the conversion of the input voltage into pulse, so that the input voltage is converted into DC voltage in proportional its frequency.
CONSTITUTION: The input voltage e is converted into a rectangular wave voltage e2 with the rectangular wave constant voltage circuit consisting of the resistor R1 and Zener diodes Z1 and Z2, and this voltage e2 is differentiated with the differentiation circuit consisting of the capacitor C1 and resistor R1, it is rectified with the diode D into pulse voltage EG. This voltage EG triggers the monostable multivibrator M to obtain the voltage Eo having a given pulse width T between the terminals 11 and 12. The voltage Eo is in proportional to the input frequency f, when the pulse width T and the voltage Vcc are constant. Further, when the pulse width is taken greater within the range of 1/f, the output voltage can also be taken greater.
