通过Python生成一个周期内正弦波数组

代码说明：

说明：  通过Python生成一个周期内正弦波数组(sine wave array.Direct digital synthesis, sine wave 0-2pi period, phase to amplitude is one-to-one correspondence.First, the sine wave query table needs to be stored, and then under the clock, through the phase accumulation module and address query module to achieve the sine wave signal.)
