Gravitational waves signals look like sine waves and occur at different frequencies that depend on their source 引力波信号看起来象正弦波，但随信号源不同具有不同的频率。
Phase angle phase angle refers to the relation between two sine waves which do not pass through zero at the same time 相角相角指的是两个不同时经过零点的正弦波之间的关系。
Gravitational waves signals look like sine waves and occur at different frequencies that depend on their source 引力波信号看起来象正弦波，但根据他们自己的震源有不同的频率。
In every signal you produce , from the sine wave frequency accuracy to the fast rise fall times of square waves , to 其好处是您能修饰所产生的每一个信号,从正弦波的频率精度方波
Using the method of firing angle prediction , steady sinusoidal output voltage with low harmonic level can be generated 通过开关角预置方法，叠加出谐波含量低的稳压正弦波输出。
