| 摘 要： | 设计用数字法直接合成正弦波的突出优点是使硬件电路简单，输出正弦波谐波含量低于基波的5dB以上，它适宜作为高精度、宽带扫频的扫描控制信号；也可作为学生的模电、数电技术课题设计的一个专题。

| Abstract: | In fact we use the digital way directly to synthesize sine wave. It is easier for us to realize the hard- ware circuit, and the content of sine wave at least by 45dB are the projecting advantages. The sine wave produced by this way can be used as the scanning controlling signal wihich is high precision and wideband scanning frequency;and it can also be used as a special subject for student's analog or digital electronic technology design of question for study. |
