A detailed examination of the digital logic Integrated Circuits (Ics) used within digital audio systems reveal modulation among the many signals generated within an individual IC, resulting in system clock jitter. In a compact disc player, digital control word signals (used for servo control, focus, etc.) and digital audio information generated from one IC affect the system clock generation found on the same IC. This jitter generation is prevalent in any digital playback system using standard IC designs. Clock jitter is measured and correlated with various digital signals.
