A Study on Analysis and Effect of Electronic Noise in an Inductive Displacement Sensor

유도형 변위 센서의 전기 노이즈 분석과 센서 성능에 미치는 영향 고찰

Noise is a problem in many electronic circuits and active control system. Arising from spuriously coupled noise from other circuits, it corrupts the signal of interest and introduces an uncertainty into information it contains. In this paper, re have researched noise characteristics of the inductive displacement sensor which has been designed. n first present basic concept and characteristics of magnetic field-coupled noise in the sensor output signal. Then, n are present relation noise and sensor performances. Finally, we concentrate low noise design of a sensor driver and a signal detection circuit.
