In today's world of high-speed technology, signal integrity and power integrity are critical components of printed circuit-board (PCB) design. Not only must designers consider layout and CAD, but they must also be able to balance the electrical and physical performance of their PCBs. This requires a deep understanding of concepts such as impedance, crosstalk, jitter, and electromagnetic compatibility (EMC). By mastering signal and power integrity, designers can ensure that their designs meet the high standards required for today's demanding applications.
