摘　　要：文章介绍了一种利用SPCE061A单片机直接合成1Hz～20KHz范围的正弦波信号发生器。波形失真小;频率控制准确,1KHz以下步进频率1Hz,1KHz以上步进5Hz。电路简单,单片机外围元件少,输出峰峰值电压2V。功耗低,工作电源电压为3V。In this paper, a Direct Digital Synthesizer sine signal generator is designed with fewer wave distortion and high frequency resolution by using a SPCE061A microchip. The frequency is adjustable from 1Hz to 1KHz per 1Hz, and steps from 1KHz to 20KHz per 5Hz. The circuit of the generator is compact with few external components. Power cost is low. The operating voltage is 3V, and the output is 2V peak to peak value.
