Coupled energy control using a variation of edge rate of trapezoidal pulse in a high-speed digital PCB

In this paper, the interline coupling of high-speed pulse propagating on printed circuit board (PCB) is investigated using the trapezoidal pulse instead of the rectangular pulse. Results show that the coupled energy of the trapezoidal pulse is less than that of the square pulse and the edge rate is the slower, the peak of the coupled energy is the less.
