These pulsations are known as the ac component of the rectifier output.
但是整流器的输出并不是纯粹的直流，而是脉动直流。
Magnitude of AC component can be specified.
可指定交流分量的大小。
DC current or voltage source. Magnitude of AC component can be specified.
直流电流源或电压源。可指定交流分量的大小。
Meanwhile, a slight AC component was added to excitation current to decoupling speed estimation and rotor resistance.
同时，为了使转速估计和转子电阻的辨识解耦，在励磁电流处叠加了小幅交流分量。
As the frequency of the AC component increases, the DC meter response decreases, until at some frequency only the average input voltage will be displayed.
当交流分量的频率增加时，直流仪表的响应就会变得不够快，直到在某一频率时，仪表只能显示出输入电压的平均值。
The DC signals after demodulation still contain AC component of one or several frequencies respectively for multiplication or diode methods, but no AC component for multiplication-Division one.
对静态位移的测量，二极管检波或乘法检波后分别得到的是一含多频或单频交流成分的脉动直流信号，而乘除法检波后信号不含交流成分。
