求翻译：输出信号通过低通滤波器将SPWM信号的谐波全部滤出掉，只剩下其基波分量，即就是系统所需要的正弦波信号。是什么意思？ 待解决

Output signal through a low pass filter to the harmonic SPWM signal to filter out all out, leaving only the fundamental component, which is required for the system sine wave signal.

output signal through low-pass filter will filter out all harmonics SPWM signals off, leaving only the kippo weight system is needed, that is the sine wave signal.

The output signal filters out completely through the low pass filter the SPWM signal overtone, is only left over its fundamental wave component, namely is the sine wave signal which the system needs.

Output signal passes through a low pass filter SPWM signal harmonic filters out all out, leaving only its fundamental component, that is, is a sine wave signal required by the system.

Output signals and finish leaching all the harmonic wave of SPWM signal through the low coherent electric-wave filter, only have its wave weight of base left, it is a sinusoidal wave signal that a system needs.
