Abstract :
High-performance, high-resolution graphics are becoming common in low-cost workstation and personal computer products. The electromagnetic compatibility (EMC) engineer responsible for design consultation on such systems must be able to analyze high-speed video signals to minimize excessive electromagnetic interference (EMI) generation while preserving >100 MHz signal bandwidth. All introduction to high-speed video signaling, and time and frequency domain analysis techniques are presented. Production quality video controllers are analyzed and compared using the described analysis techniques
