Transmission of multimedia signals is commonly encountered in our daily life. Besides the researches in the base-band processing, transmission of multimedia signals is also an important branch. For transmission, the external power supply is inevitable, and the PC switching power supply produces the conducted emissions. These emissions usually can be reduced by using electromagnetic interference (EMI)...
In general, the conducted electromagnetic interference (EMI) emission exists in most of the electronic products and affects the electromagnetic environments. In this paper, we design a switching circuit to observe and improve the conducted EMI emission. We also discuss the conducted EMI effects with putting RC snubber or diode into the switching circuit. It is found that the switching circuits with...
