我们常见的电源有线性电源和开关电源,它们输出的直流电压是由交流电压经整流、滤波、稳压后得到的。由于滤波不干净,直流电平之上就会附着包含周期性与随机性成分的杂波信号,这就产生了纹波。如何正确测量你的电源纹波噪声呢?
Our common power sources include linear power sources and switching power sources, whose output DC voltage is obtained by rectifying, filtering, and stabilizing the AC voltage. Due to poor filtering, clutter signals containing periodic and random components will be attached above the DC level, resulting in ripples. How to accurately measure the ripple noise of your power supply?
