An analog signal is composed of four basic components: DC and AC magnitudes, frequency, and phase.
模拟信号由直流和交流分量、频率和相位四部分组成。
Therefore it can be seen that it will "smooth" the "twice mains frequency DC" into a near constant DC voltage.
因此它可以把“两倍于电源频率的直流电”进行“平滑化处理”，成为一个接近恒定的直流电。
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。
