ABSTRACT:
In a computer or other digital system a double side band suppressed carrier (DSB-SC) signal is derived from a clock or other synchronous signal. The clock or other synchronous signal is amplitude modulated at a source using a broadband low frequency envelope signal. The modulated signal is the DSB-SC signal, which then serves as a clock or other synchronous signal for the source and/or a destination circuit.
