Meaning Signal blocker Jamming

Over long distances, the signal is degraded by attenuation, noise, and interference from other wires in the bundle. An analog signal can be amplified periodically, but if the signal is corrupted by noise, a distorted signal is amplified.The period of the periodic noise component of the communication signal is determined by correlating the communication signal with the communication signal delayed by different delay amounts.

When two or more different frequency signals act on a nonlinear circuit, the signal jammer will modulate each other to generate a new frequency signal output. If the frequency falls within the working channel bandwidth of the receiver, it will interfere with the receiver and become intermodulation interference. Any receiver has a certain receiving dynamic range. When the out-of-band interference signal is strong to a certain extent and the receiving power exceeds the maximum power level allowed by the receiving dynamic, the receiver will be saturated and blocked, thereby affecting the receiving performance of the system. This kind of interference called blocking interference. Blocking can cause the receiver to not work properly, and long-term blocking may also cause permanent performance degradation of the receiver.
