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。
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.
用加窗的DFT方法，从正弦波的DFT主瓣的幅度来计算正弦波的均方根值(RMS)，最好使用最小能量窗。
It's better to select the minimum energy window to calculate RMS of sine wave by using the window DFT on the basis of the amplitude of sine wave DFT main lobe.
