Signal Integrity

Ensure reliable high-speed signals across PCBs and interconnects.

Electrical Engineering • Signal Integrity & High-Speed Digital Design🔥 Advanced

Signal Integrity covers how signals propagate through interconnects and how to prevent distortion, reflections, crosstalk, and EMI in high-speed digital systems. Learners will understand transmission-line behavior, measurement methods, and practical PCB/layout strategies to preserve signal fidelity.
