The deviation of the signal amplitude (ΔA) is defined as the amplitude noise (or simply noise), and the deviation of time (Δt) is defined as the timing jitter (or simply jitter). Those definitions will be used throughout this book. The impacts of timing jitter and amplitude noise are not symmetrical, though. Amplitude noise is a constant function and can affect system performance all the time. [AdSense-A]
