直流电源通过线性方法或开关方法将交流（AC）电转换为直流电。 开关电源的效率更高、重量更轻、外形更小巧。 线性电源可以实现更低的噪声，但在现代开关电源面前，这已经不再是一个优势。
An oscilloscope uses a probe to connect to a test point in a circuit and amplify or attenuate the voltage at that point. The subsequent signal path depends on the oscilloscope, but in general, analog circuits condition the signal and analog-to-digital converters digitize it for further evaluation, processing, and analysis. ,
