Signal blocker Jamming Technology

The types of interference are usually divided according to the cause of jamming signal, the interference pattern of the noise, and the waveform characteristics of the noise. Among them: according to the different causes of noise, it is divided into discharge noise, surge noise, high-frequency oscillation noise, etc.; according to the waveform and nature of the noise, it is divided into continuous noise, occasional noise, etc.; according to the different sound interference modes, it is divided into are common noise mode interference and differential mode interference. Common mode interference and differential mode interference are more commonly used classification methods.

Under the action of the changing magnetic field, an induced current will be generated in the shielding layer, which will interfere with the signal loop through the coupling between the shielding layer and the core wire. If systematic ground is confused with other grounds, the resulting ground loops may produce uneven potential distribution on the ground wire.The shielding layer, the ground wire and the ground may form a closed loop. Under the action of the changing magnetic field, an induced current will appear in the shielding layer, and the signal circuit will be disturbed through the coupling between the shielding layer and the core wire.
