Method and system for eliminating electromagnetic interference

The invention provides a method and system for eliminating electromagnetic interference. In addition to a first cable, a second cable for transmitting interference signals is further arranged in the system, processors are arranged at the output ends of the first cable and the second cable, the processors can extract a useful signal in the first signal based on the first signal and the second signal. In the method and system provided by the invention, signals transmitted by the first cable and the second cable need only be transmitted to the processors, no anti-interference filter needs to be installed in the molded device, so the structure of the molded device is not changed, and the electromagnetic interference can also be filtered out. 本发明提供了种消除电磁干扰的方法及系统，本发明中除了设置有第电缆外，还设置有传输干扰信号的第二电缆，并且在第电缆和第二电缆的输出端设置有处理器，进而处理器就能够根据第信号和所述第二信号，提取出所述第信号中的所述有用信号。本发明中只需要将第电缆和第二电缆传输的信号传输到处理器中即可，不需要在已成型设备中安装抗干扰滤波器，进而也不会改变已成型的设备的结构，并且还能够滤除电磁干扰。
