Eliminate the car sound of the current noise There is no noise when the car is not started, and there is noise after the car is started. This phenomenon is mostly caused by the interference of car electrical appliances on the car audio power supply. Installing a power filter can eliminate these noises. 2. Eliminate the reverse image screen In some models of German cars and American cars, after the engine is started, the output voltage interferes greatly. The power supply for the reversing lights is not a pure DC power supply, but a pulse signal is superimposed on it. If the conditions can be tested by an oscilloscope, it is found that Square wave-like signal. If the reversing camera does not have a filter, the power supply line of the camera is directly connected to the reversing light. Because the working voltage is very unstable, the camera does not work very often and the video signal output is not normal. to the screen. 3. Elimination of electromagnetic interference of HID lamp ballast HID lamp ballasts light the lamp by generating instantaneous high voltage, which will generate electromagnetic interference, which can be eliminated by installing a power filter.
