The changing electric field produces the changing magnetic field, and the changing magnetic field produces the changing electric field. This is the principle of electromagnetic wave generation and transmission. The changing magnetic field is generated by the change of magnetic flux in the line through which the changing current flows, because this introduces electromagnetic interference,…
If the frequency of the digital logic circuit reaches or exceeds 45MHZ~50MHZ, and the circuit working above this frequency has accounted for a certain proportion of the entire electronic system (for example, 1/3), it is usually called a high-frequency circuit. High-frequency circuit design is a very complex design process, and its wiring is crucial to…
Electromagnetic compatibility refers to the ability of electronic equipment to work in a coordinated and effective manner in various electromagnetic environments. The purpose of electromagnetic compatibility design is to enable electronic equipment to suppress various external interferences, so that electronic equipment can work normally in a specific electromagnetic environment, and at the same time reduce…

For people who study electronics, setting test points on PCB is a natural thing, but for people who study mechanics, what are test points? Basically, the purpose of setting test points is to test whether the components on the circuit board meet the specifications and solderability. For example, if you want to check whether there…
When RF circuits are designed according to a pre-set scheme, their performance may not be fully up to standard. An important factor that causes RF performance to fail to meet standards may be electromagnetic interference. Electromagnetic interference is not necessarily caused by unreasonable circuit layout and wiring in the RF field, but may also be…

This article summarizes some methods for everyone. 1.The following systems should pay special attention to anti-electromagnetic interference: (1)Systems with extremely high microcontroller clock frequencies and extremely fast bus cycles. (2)Systems containing high-power, high-current drive circuits, such as spark-generating relays, high-current switches,…
1 Generation and suppression principle of EMI EMI is generated by the electromagnetic interference source transferring energy to the sensitive system through the coupling path. It includes three basic forms: conduction through wires or common ground wires, radiation through space, or coupling through near fields. The harm of EMI is manifested in reducing the quality…
