Jitter determination for digital data signals separating random jitter from deterministic jitter

摘要

For determining a corrected jitter value of a digital data signal to be measured, a reference jitter value is determined from a reference measurement for a first digital signal with substantially no data dependency, the reference jitter value representing an amount of jitter detected for the reference measurement. A jitter value is determined from a data measurement for the digital data signal, the jitter value representing an amount of jitter detected for the data measurement. The corrected jitter value (JD) is derived by a subtraction of the determined reference jitter value and the determined jitter value. <IMAGE>
