Abstract
PURPOSE: To make it possible to obtain high-precision and stable characteristic by using a counter output and a polarity decision circuit output to convert the repeat frequency of input pulses to a digital value.
CONSTITUTION: An F/V converter has phase decision circuit 11, adder circuit 12, clock pulse generator 13, pulse synchronizing circuit 14, and reversible counter circuit 15 for the purpose of counting the repeat frequency of two input pulses PA and PB. Further, the F/V converter has D/A converter 16 to convert counted pulse repeat frequencies to DC voltages and polarity addition circuit 17 to control the polarity of output voltages. Further, a feedback system consisting of absolute value circuit 18, V/F converter 19, and pulse synchronizing circuit 20 is provided for the purpose of check whether converted DC voltages become a normal value or not, and the feedback pulse is supplied to reversible counter circuit 15. The polarity of output DC voltages is determined by polarity decision circuit 21.
