摘要
介绍一种用数字电路设计的PWM调制器。与用模拟运放设计的PWM调制器或专用集成PWM调制器相比,此调制器具有制作容易、成本低廉、不存在零点漂移,便于与计算机接口等特点。
A sort of PWM(Pulse Width Modulate)modulator that desinged by digital circuit is introduced in this paper.Compared with those by operate amplifier or special IC.it has many advantages as follows:easy to make,cheap,no zero excursions,convenient for connecting with microcomputers and so on.
