Abstract
In a computer or other digital system a clock or other synchronous signal is routed from a source to a destination as a double side band suppressed carrier (DSB-SC) signal. The clock or other synchronous signal is amplitude modulated at the source using a broadband low frequency envelope signal. The modulated signal is the DSB-SC signal, which then is routed over PC board traces to the destination. At the destination, the DSB-SC signal is demodulated to achieve the clock or other synchronous signal.
