Result indicates that the spectrum gained from using W-O way comprises much fewer side lobes and achieves higher energy ratio of main lobes to the first side lobe.

结果表明，W - O方法得到的信号频谱比传统加窗具有更少的旁瓣干扰和更高的主瓣-第一旁瓣能量比。

This ratio is called as the side lobe level (expressed in decibels).

这个比值叫做旁瓣电平(以分贝数表示)。
