ABSTRACT:
Multiple controllable delays reduce EMI radiated during the transmission of multiple synchronized signals. Each controllable delay introduces a controlled delay into a corresponding signal being transmitted. The controlled delay is such that the combined strength of the multiple signals at peak frequencies is substantially reduced. This results in reduced EMI radiation at those peak frequencies.
