Abstract

PURPOSE: To generate the voltage corresponding to the input signal frequency free from effect of ripples, etc. by correcting the voltage corresponding to the specified reset period of an integrating circuit with an addition amplifier and performing integration according to signal period.
CONSTITUTION: A constant pulse generator 1 outputs the pulse of a short width according to the rise of input pulses and resets an integrating circuit 3 at the specified period. Then, when the voltage corresponding to the reset period of the circuit 3 of an addition amplifier 10 is integrated by the circuit 3 and becomes higher than a specified level, a switch 6 is closed via AND circuit 5 by the detection output of a threshold value detector 4 and the integrated voltage having been corrected of the reset period through the amplifier in the period excluding the reset period of the circuit 3 is applied from the circuit 3 to a mean value amplifier 2, thus the voltage having been converted in correspondence to the input frequency without effect of ripples, etc. may be generated.
