다국어 초록 (Multilingual Abstract)
Abstract - This study describes a method developed to reduce electromagnetic interference induced to bio-potential ECG amplifier with the Driven -Right-Leg circuit when human body contacts earth ground, accidentally. Since the contact between body and earth ground disturbs the presumed operation of the Driven-Right-Leg circuit, the ECG signal includes serious interference level, preventing ECG signal analysis by formal methods. To decrease the current flow to the Driven-Right-Leg circuit, a resistor is added between the output of the circuit and the amplifier common. Experiment has shown that the modified circuit reduces the interference level significantly both during body contact to earth ground (~1/5) and during without contact(~1/2).
