There are some pulse competition in the digital naturalsampling based SPWM.
SPWM数字化自然采样法存在脉冲竞争现象。

When sampling frequency is quite high, frequency spectrum distributing of digital naturalsampling and naturalsampling is similarity.
当采样频率比较高时，数字化自然采样法的频谱分布与自然采样法的频谱分布类似。

As the naturalsampling method generating SPWM pulses closer to sine wave is impractical in real-time control, the regular sampling method with poor precision is usually adopted in practical projects.
