PCB design and internal wiring with reduced EMI (electromagnetic interference) for flat Tv applications

In this thesis, a design guide constructed with theoratical info for tv applications with a low electromagnetic interference which is almost mandatory in recent times for both technical benefit and commercial trading. This report recommendates fruitful ideas for design and troubleshooting.Electronic products may often unexpectidely produce radio?frequency (RF) energy. Therfore, these kind of devices have the potential of causing unwanted interference with this energy, which is called Electromagnetic Interference (EMI). EMI is actually the process by which disruptive electromagnetic energy is transmitted from one electronic device to another via raidated or conducted paths. TV is one of the most used electronic product in daily life. And it?s used with other electrical and electronic products in the areas of concern when unintentional sources of RF energy may be observed. As digital and high-frequency systems are increasingly developoed in TV applications and other consumer products, EMI becomes a wider concern.In this thesis, a design approach for TV applications is constructed in order to save time and money. According to regulations in Europe, it is necessary to pass some tests related to EMI to take a place in Eurepean market. This feature of regulations is related electromagnetic compatibility (EMC). For those companies that send TV blindly to test-laboratory hoping the best and get their unit with failing results, it becomes the responsibility of someone back at the factory to tackle this problem. Therefore a guidance is needed at this point .
