Description: 对噪声抵抗能力的增强是PWM相对于模拟控制的另外一个优点，而且这也是在某些时候将PWM用于通信的主要原因。从模拟信号转向PWM可以极大地延长通信距离。在接收端，通过适当的RC或LC网络可以滤除调制高频方波并将信号还原为模拟形式。 -Noise resistance to increasing ability of the PWM is relative to the simulation control another advantage of, and this also is in some time will be the main cause of PWM used for communication. From the analog signal to PWM can greatly extend the communication distance. In the receiver, through the appropriate RC or LC network can filter out square wave and high frequency modulation signal for simulating the reduction form. Platform: |
