Abstract
PURPOSE:To obtain the frequency characteristic of a common mode noise rejection rate as a higher value from a low frequency to a high frequency by providing a variable resistor in series with a resistor of a filter circuit. CONSTITUTION:An RC filter comprising resistors 1, 2, 3 and a capacitor 4 forms a filter for rejecting normal mode noise 8 having a time constant T1 expressed in equation I. An RC filter comprising the resistors 1, 3 and a capacitor 5 forms a filter having a time constant T2 expressed in equation II. An RC filter comprising the resistor 2 and a capacitor 6 forms a filter having a time constant T3 expressed in equation III. In selecting the time constants T2, T3 equal to each other, the common mode noise 9 applied to the noninverting and inverting input of an amplifier 7 is applied equally to them. Moreover, the noise voltage fed to the amplifier 7 is attenuated by the filters having the time constants T2, T3 respectively.
