摘要：(57)< Abstract > < Objective > Removal of the frequency component of the

specification which is included in the electric informationThe notch filter circuit which is

made purpose is known, butIn twin T die notch filter circuit two variable resistorsSo there

to be an inconvenience which is adjusted, in addition, in the LC resonance die circuitThe

variable resistor is one, but when configuration frequency is changed, the decreaseThere

is a problem that the tonnage changes. As for this proposition, decreaseTo provide each

one variable resistor with for the tonnage and frequency, at the same time,Becoming

independent, offering the filter circuit which you can adjust objectWith it does. <

Constitution > From 3 fixed resistors and one operation amplifierru differential amplifier

and 2 fixed resistors and the variable resistance 1Capacity of the vessel and 1 and the

inductor which consists of one operation amplifierFrom the nsu simulator circuit and the

capacity 1 it is constitutedResonance circuit and, capacity 1 and inductance shimiyureThe

circuit which interposes 1 variable resistors in series with the ta circuitIt consists.
