一个与一个低通滤波器结合可以用作简单、廉价的数/模转换器。其输出可用于驱动电压控制器件，或用于需要模/数转换器采样受控参数的反馈控制系统中。PWM常用于电机控制系统中。-A combination of a low-pass filter can be used as a simple, low-cost D/A converter. The output can be used to drive voltage control devices, or for the need for A/D converter sampling the controlled parameters of feedback control systems. PWM motor control commonly used in the system.
