PURPOSE:To obtain a converter which can make input and output characteristics of positive polarity and negative polarity different and also convert the both into linear characteristics and nonlinear characteristics respectively by using a proportional operational amplifier, integrator, monostable multivibrator, etc. CONSTITUTION:As for input and output characteristics, proportional operational amplification part 1 generates a linear characteristic output whose gain can independently be set across input ei=0 and outputs 01 and 02 are applied to integrator 2 and inversional amplification part 3. Adding amplification part 4 generates the inversion output of gain 1 at output terminal Q5 when the sum of outputs of integrator 2 and inversional amplification output 3 has the positive polarity or at output terminal Q6 when the negative polarity. Comparator 6, when output Q5 reaches a prescribed value, generates the output to trigger monostable multivibrator 8, and comparator 7, when output Q6 reaches the prescribed value, generates the output to trigger monostable multivibrator 9. Resetting circuit 12 resets integrator 2 only during the output period of monostable multivibrator 8 or 9. |
