1, check the wireless network card and wireless router distance is suitable, when the distance between them is very far, may wish to shorten their communication distance, and remove the obvious obstacles between them all to increase the wireless network card signal reception ability. If the distance between them cannot be adjusted, antennas can be used to appropriately expand the wireless network signal coverageCover the range. Check whether there are strong signal interference sources around the wireless network.
2, the frequency of the interference signal is the most common parameter to identify the source of interference, therefore, it is usually possible to classify the interference signal according to the frequency characteristics. It should be pointed out that regardless of whether the interference signal is in or out of the frequency band, the signal must pass through the antenna, the cable, and then into the affected receiver. Therefore, a spectrum analyzer connected to an OS antenna can be used as a measurement receiver to display and identify unwanted signals. Interference usually only affects the performance of the receiver.
3, the detection and reduction of wireless interference can be usedThe AP that provides access services can also be scanned by a network composed of specialized devices, and even can be cooperated with specialized handheld RF devices for interference positioning, which is generally suitable for small networks or small range of accurate positioning.

5, how to determine whether the bridge is disturbed? passableThrough the monitoring screen to observe, if there is a packet loss, screen instability, clutter, black stripes or ripples and other phenomena, it indicates that the equipment may be interfered with. At this point, you should check one by one to determine the cause of interference. It's important to note that not all devices interfere with wireless signals. For example, mobile phones, walkie-talkies, and cordless phones generally have no effect on wireless microwave devices.
6, Analyze the possibility of RF interference You may need to do this before installing the wireless network, may wish to analyze by RF field investigation. Also, talk to people at the facility about other radio frequencies that may be in useEquipment. This will give you information that can help you decide what actions you need to take to reduce distractions.
Do not know wireless charging waveform analysis , what do you want to study? Approximate principle 433mhz is just a carrier frequency wireless charging waveform analysis , debugging is to leave a useful signal wireless waveform analysis , filter out excess waveform, such as 433mhz once the useful signal is received, there is no need for 433MHZ frequency wireless waveform analysis .
According to a circuit diagram on the Internet, SC2262 and SC2272 chips are used as remote control circuits. T10A transmitter module and XY-R04A receiver module are used on the circuit. Who has the detailed circuit diagram of these two modules and the entire circuit? ... Appeal to friendsHelp.
and 2272 on both sides of the RC oscillation circuit frequency to match, it is necessary to choose a pair of suitable matching resistance, otherwise it can not be correctly decoded. The recommended value of the general matching resistance is: 2262 2M Wireless charging waveform analysis ; 2272 200K.
Fixed code remote control, also known as the code remote control, welding code remote control, commonly used transmitter chip PT, SC, HS, LX (2260/2262/2264), paired receiving chip PT, SC, LX, HS (2270/22Reduce noise.
2, one of the ways to solve the problem of sound buzz is to check and adjust the connection. First, make sure all cables are securely connected and plugged properly. Try replacing the existing cable with another cable to rule out the problem with the cable itself. Second, check whether the ground connection of the audio and other equipment is good. Making sure your stereo and other equipment is grounded properly can alleviate the buzzing problem to some extent.
3, the sound noise, you should first check the location of the audio, the connection line, and adjust the volume, if the problem is still, you may need to check the audio equipment itself or seek professionalTechnical help. When there is a loud sound problem, the first thing we need to check is the placement of the sound. Improper stereo placement may cause noise problems. For example, if the sound is near a wall or other reflective surface, it may cause the sound to echo and increase in noise.
4. Open the distance between the speaker and the microphone. This reduces the chance that the microphone will pick up the sound being played on the stereo. (2) Reduce the sensitivity of the microphone. This can reduce the intensity of the sound captured by the microphone, thus reducing the possibility of feedback loops. (3) Use directional microphone. Directional microphones only capture from specific sourcesDirectional sound reduces the chance of picking up ambient noise. (4) Use audio processing software or equipment.
5, keep a distance: try to stay away from the bar stereo and speakers, keep a distance can reduce noise hazards. Regular breaks: Try to get away from the noise of the bar during work breaks to rest your ears and reduce the risk of hearing damage. Wear soundproof earplugs or earmuffs. You can choose professional acoustic earplugs or earmuffs, which can effectively isolate noise and protect your hearing.
6, the main speaker in the permitted conditions, as far as possible away from the computer host, and reduce the surrounding wireless equipment, according to thisMethod to do, the sound will decrease or disappear if there is current in the stereo. A rubber damping layer can be installed between the transformer and the fixed plate. Thermal noise can be reduced by replacing low-noise components or reducing the workload of components, and the operating temperature can also be reduced.
