摘要
任意波形发生器作为信号源，在实验教学和实际工作中有着广泛的应用；应用Intel公司80C196KC单片机的HSO功能产生PWM波形，再由PWM波合成频率在20-100Hz之间的任意波形；设计了具体的硬件控制电路和详细的软件实现方法，并以三相SP—WM波形发生器为例，给出了实际应用电路及其测试结果；实验结果表明，该波形发生器产生的三相正弦波、三角波、锯齿波失真度小，操作简单，直观，性能价格比高。
Arbitrary waveform generator is widely used in experiment and practical work as signal source. Apply the HSO function of 80C196KC MCU to generate PWM waveform, then use the PWM to compose arbitrary waveform. The concrete hardware control circuit and the software realization method are presented. Then take the three-phase SPWM waveform generator for example, put forward the application circuit and show the result of test.. Experiment shows that the waveform distortion of sine, triangle and sawtooth is small and the operation is simple. The performance is high.
