在一些电路教材中常把带滤波器的整流电路作为一个实例，用以讲述用傅立叶级数的谐波分析方法来求解非正弦电路。

In some circuit textbooks the rectifier circuit with the filter has been used as an example to illustrate the harmonic analysis of nonsinusoidal circuit adopted Fourier series.

当输入电压为正弦交流电压时，非晶薄带磁感应效应变化幅度的不重复性误差很小，且受温度和湿度的影响小。

The non-repeatability error and influence induced by temperature and humidity are small when the input voltage is sinusoidal.
