Zusammenfassung:An apparatus for generating an output signal that is analogous to an first signal from a first signal source that exhibits a first jitter, so that the output signal exhibits less jitter than the first jitter includes at least one second signal source generates a second signal that is analogous to and phase locked with the first signal. The second signal exhibits a second jitter that is uncorrelated with the first jitter. A signal averaging device is responsive to the first signal and the second signal. The signal averaging device averages the first signal and the second signal with respect to at least one parameter and thereby generates the output signal.
