ABSTRACT:
A circuit for shielding an electro-magnetic wave noise radiated and conducted from a wiper motor is disclosed. The circuit absorbs, shields or suppresses such electro-magnetic wave noise when the wiper motor is activated to drive the wiper under a particular weather condition such as rain or snow. The different components of the electro-magnetic wave noise are absorbed or suppressed by different circuit components, so that the electro-magnetic noise could not reach safety devices of the automobile. Therefore accidents can be prevented, and riders can be protected.
