Continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity.

Avoid Critical Signals in Edges of the PCB
When routing a printed circuit board (PCB), try to avoid critical signals in emissions or immunity close to the edge of the board to create a more robust system for EMI and EMC.
A Discussion on Low-Cost Printed Circuit Board Design
Low-cost designs are often an underserved and challenging part of a layout engineer’s career and getting increasingly complicated.
Impact of 3D IC Design on ESD Protection
Slots in GND Planes
Many of the EMI/EMC problems in electronic products can be avoided or solved with ground (GND) planes. But, be sure your GND plane is a true GND plane.
Protecting Industry from HEMP and IEMI
Protection from high-altitude electromagnetic pulse (HEMP) and intentional electromagnetic interference (IEMI) is an important consideration to the design of modern electronic systems, especially those that control critical infrastructures.
