PURPOSE:To make an average value calculation firm at high speed by commonly connecting a plurality of input terminals respectively equal resistance and conducting out an output terminal from the connecting point between a high resistance impedance and these resistances. CONSTITUTION:To an input terminal (a), the resistance R1, is connected, to an input terminal (b), the resistance R2 is connected, the other ends of the resistance R1, R2 are commonly connected, the high resistance impedance R1 is connected to the connecting point (c) and the other end thereof is connected to an earth. Then, R1=R2 is obtained and further, the output terminal (d) is conducted out from the connecting point (c). Accordingly, the average value Vo of input voltage V11 and V12 inputted to the input terminal (a) and the input terminal (b) can be obtained. Thereby, the average value calculation can be made firm at high speed. |
