A NOISE CUT TRANSFORMER WITH NOISE DISPLAY UNIT AND IMPEDANCE MATCHING UNIT

摘要

PURPOSE: A noise cut-off transformer equipped with a noise displaying part and an impedance matching part is provided to secure the driving stability of the transformer by automatically matching power impedance and input-output impedance. CONSTITUTION: A noise bandwidth filter(300) filters voltages or currents through a power cut-off part. A noise detecting part(400) amplifies the filtered voltages or currents and detects the voltages or the currents. A micro computer(700) outputs the cut-off degree of noise according to the signal size of the voltages or the currents. A noise displaying part(500) displays the signal size of the voltages or the currents and the cut-off degree of noise.
