Abstract
The embodiment of the invention provides a server wireless signal receiving anti-interference protection circuit, comprising an inductor, a resistor, a first capacitor, a second capacitor, a third capacitor and a fourth capacitor. One end of the inductor, one end of the second capacitor and one end of the third capacitor are connected with a live wire. The other end of the second capacitor is connected with a neutral wire. The other end of the third capacitor is connected with a ground wire. One end of the fourth capacitor is connected with the ground wire. The other end of the fourth capacitor is connected with the neutral wire. One end of the resistor is connected with an output negative end. The other end of the resistor is connected with the neutral wire. The first parameter is connected with an output positive end and the output negative end in parallel. The other end of the inductor is connected with the output positive end. According to the server wireless signal receiving anti-interference protection circuit provided by the invention, a harmonic signal mixed up with a power supply can be filtered, and a portable computer is not influenced by the harmonic signal in the power supply when receiving a wireless signal.
