Abstract
A method for transmission of high-speed digital signals includes transmitting a data signal over a communication line responsive to input data, the data signal having a data frequency spectrum. During an idle interval in the input data, two idle signals are transmitted in alternation: a first idle signal, having a first frequency spectrum that is substantially stationary relative to the data frequency spectrum, and a second idle signal, having a second frequency spectrum that is substantially non-stationary relative to the data frequency spectrum.
