Description

Electronic information anti-interference equipment

Technical Field

The utility model belongs to the technical field of electronic information anti-interference, and particularly relates to electronic information anti-interference equipment.

Background

The video anti-interference device is the best auxiliary tool for solving the video interference problem in video monitoring. The anti-interference equipment mainly has two modes, namely a frequency shift anti-interference mode, and the mode can thoroughly solve interference; another way of amplifying the interference is that the interference rejection device is not capable of eliminating the interference in principle, but is indeed effective in reducing the amplitude of the interference signal. Assuming that the output amplitude of the video signal is U1 and the amplitude of the interference signal is U2, the amplitude of the video signal arriving at the terminal is the sum of the source signal and the interference signal, i.e., u1+u2 (without considering the attenuation problem of the signal itself), wherein the interference signal having the amplitude of U2 causes serious interference to the image displayed on the monitor screen. If the amplitude of the original video signal at the front end is amplified by n times to Nu1 by an amplifier before the transmission, after the transmission, the interference signal of U2 is mixed in, the signal reaching the terminal becomes nu1+u2, the amplitude obviously exceeds the requirement of the input level allowed by the display device, so that an attenuator is required to attenuate the composite signal mixed with the interference signal received at the terminal by n times as a whole to obtain (nu1+u2)/n=u1+u2/n, and as a result, the signal amplitude at the terminal is recovered to U1, and the interference component is changed to U2/n. Therefore, after the processing of amplifying and then compressing the signal, the video signal output to the display device can still keep the original amplitude unchanged, and the amplitude of the interference signal is reduced by n times. That is, the original strong interference becomes weaker and the original less strong interference becomes less noticeable, as seen solely from the monitor screen.
