In this course, you will learn how to design a radio-electronic device so that it passes EMC tests the first time.
The course reveals the secrets of the practical application of knowledge gained by engineers over 20 years, specialists conducted more than 10,000 experiments in EMC laboratories and developed a unique author's technique from Trushanin Evgeny Nikolaevich to combat interference and radiation from the product.
The course describes in detail ready-made schemes for combating EMC interference, which work 100% and have been repeatedly tested in the laboratory.
In the course, the principles of building protection and shielding of products from increased radiation are written in an accessible language, it is explained on the fingers how to ensure 100% of the EMC requirements without increasing the cost of the product.
