摘　　要：针对传统正弦信号发生器存在元器件多、体积大、结构复杂、稳定性差、信号参数不宜调节及精度低等诸多缺陷,在分析C8051F005单片机性能特点的基础上,设计了基于C8051F005的数字式正弦函数发生器,并详细介绍了正弦函数发生器的原理。该发生器具有体积小、控制方便、波形稳定、精度高等优点。程序稍作修改还能生成并输出任意波形,如三角波、方波、锯齿波等。In the light of defects in traditional sine signal generator, e.g. abundant components, complex construction, bad stability, uneasy adjusting of signal parameters, and low precision, and through analyzing the performance and features in C8051F005 single chip computer, the digital sine function generator by using C8051F005 is designed. The principle was introduced in detail. This generator possesses the advantages of small volume, convenient control, stable waveform, and high precision. If the programs are slightly changed, any waveform can be generated and output, such as triangle wave, square wave and zigzag wave, etc.
