Title:
METHOD AND SYSTEM OF REDUCING ELECTROMAGNETIC INTERFERENCE EMISSIONS
Document Type and Number:
WIPO Patent Application WO2003067379
Kind Code:
A3
Abstract:
A method and system is disclosed for spreading the power associated with digital signals being transmitted in reducing electromagnetic (EMI) emissions in a bit stream. After being transmitted across a transmission line (169), a representation of the original digital signal is recovered and provided to a destination device.
