SIGNAL PROPAGATION SYSTEM AND METHOD OF REDUCING ELECTROMAGNETIC RADIATION EMISSIONS CAUSED BY COMMUNICATION OF TIMING INFORMATION

摘要

A signal propagation system for communicating timing information comprises a processing resource (300) arranged to generate a first timing signal for communicating the timing information, the first timing signal having a first frequency spectrum associated therewith. An electronic circuit (110) is provided having an input for receiving the timing information. An electrical connection (310) between the processing resource (300) and the electronic circuit (110) is also provided. A signal transformation module (304) for communicating the timing information, and the signal transformation module (304) is arranged to translate the first timing signal into a second timing signal for communicating the timing information. The second timing signal has a second frequency spectrum associated therewith that comprises fewer harmonics than the first timing signal, thereby reducing electromagnetic energy emitted by the electrical connection.
