摘要
介绍一种用８０９８单片微机的高速Ｉ／Ｏ口直接产生双边调制ＳＰＷＭ波的方法．此法充分利用了８０９８单片微机的资源，外围元器件大幅度减少，系统可靠性有很大提高；
The author describes a method that generates directly double edge modulating SPWM waveform by high speed I/O ports of 8098 single chip computer. By this method, the resource of 8098 single chip computer is utilized fully, the quantity of the auxiliary components is reduced. The system is reliable and has been used in practice.
