Abstract: A printed circuit board of an information handling system includes a dielectric layer, adjacent differential pairs, a ground layer, and a ground wall. The adjacent differential pairs are plated on the dielectric layer, and generate crosstalk between each other. The ground wall is in physical communication with and electrically coupled to the ground layer. The ground wall extends substantially perpendicular from the ground layer through the dielectric layer. A top surface of the ground wall is a specific height above a top surface of the adjacent different pairs. The ground wall suppresses the generated crosstalk based on the specific height and a width of the ground wall.

The technique further includes providing a script for use by a 3D modeling subsystem. The script includes a set of circuit board design values based on the set of individual circuit board dimension parameters formed for each layer. Other properties such as layer width and thickness, via dimensions, etc. are handled in a similar manner.

Abstract: A method and apparatus for dynamically controlling the threshold of the onset of dynamics processing in an audio system is provided. In an audio system, the onset of dynamics processing is controlled by varying a control point. The control point is moved by an audio engineer or other means. By changing the position of the control point, the audio engineer is also changing the threshold of onset of dynamics processing, so as to provide a dynamic safety net. Thus, when the engineer moves the control point to a given position, the threshold of onset of dynamics processing moves to a new position which is proportional to the position of the control point, and effectively provides a window through which audio may exit the system unprocessed by the dynamics processor. Regardless of where the control point is positioned, the onset of dynamics processing will depend on the position of the control point and the amount of offset being applied to the threshold.
