Abstract
A method and system is disclosed for spreading the power associated with digital signals being transmitted to reduce electromagnetic interference (EMI) emissions by receiving, via a first transmission line, a first power spread signal representative a first digital signal modified using a first power spreading digital noise signal, modifying the power spread signal using a second power spreading digital noise signal substantially similar to the first power spreading digital noise signal to generate a second digital signal substantially similar to the first digital signal, modifying the second digital signal using a third power spreading digital noise signal to generate a second power spread signal and providing the second power spread signal for output to a second transmission line.
