Electromagnetic compatibility considers the problems of equipment cohabitation and develops methods to control, predict and resolve the effects of various disturbances:
Signal integrity handles disturbances in the equipment itself: signal distortions during its propagation on networks, from cable to integrated circuit via connectors, printed circuits boards (PCBs) and electronic packages.
Audio-video applications currently require higher and higher transmission speed and signal processing circuits, which leads to an ever-larger spectral occupation and thus to higher frequencies to be transmitted. At the same time, the presence of multiple parasite phenomena limits the bandwidth of the transmission channel:
Thus, the transmission of the signal across a limited bandwidth transmission channel composed of packages, connectors and lines is manifested by distortions that can ...
