1、 In the field of electromagnetic compatibility (EMC), why is it always described in decibels (dB)? Answer: Because the range of amplitude and frequency to be described is very wide, it is easier to express it in logarithmic coordinates on the graph, and dB is the unit when expressed in logarithm.

In recent years, the macro environment has been changeable, and the epidemic has repeatedly affected the domestic electronic industry chain. The continuous fermentation of the "core shortage tide" has brought difficulties to the supply of materials in the market, and has also indirectly promoted the proliferation of fakes, seriously endangering the normal supply chain order. Driven by the market demand, domestic chips are increasingly replacing the original position of imported chips by virtue of their excellent cost performance ratio and localization services. However, the majority of terminals still need professional solutions to deal with the selection, testing, development and other problems of alternative solutions. View >>

MOS tubes are metal oxide semiconductor field effect transistors, or metal insulator semiconductor. The source and drain of MOS tube can be exchanged. They are both N-type regions formed in the P-type background. To correctly test and judge whether MOSFET fails, the key is to find the reason behind the failure and avoid making the same mistake again. This paper has collected and sorted out some data, hoping to be of great reference value to all readers. View >>

The full name of EMC test (electromagnetic compatibility test) is Electro Magnetic Compatibility, which is defined as the ability of equipment and systems to work normally in their electromagnetic environment without causing unbearable electromagnetic interference to anything in the environment. Therefore, the EMC test includes two requirements: on the one hand, the electromagnetic interference generated by the equipment to the environment during normal operation cannot exceed a certain limit; On the other hand, it means that the appliance has a certain degree of immunity to electromagnetic interference existing in the environment, that is, electromagnetic sensitivity.
