  • Reduced EMI device and method thereof
    Patent number: 7386028
    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.

  • Method and system of reducing electromagnetic interference emissions
    Patent number: 7305020
    Abstract: A method and system is disclosed for spreading the power associated with digital signals being transmitted to lower electromagnetic interference (EMI) emissions. After being transmitted across a transmission line, a representation of the original digital signal is recovered and provided to a destination device.
