Patent ID: 7149638

Claim:
A method for separating random and deterministic components of jitter comprising the following: using a measured value for deterministic jitter and a plurality of values for random jitter to calculate a plurality of first ratios (ξ ml ) of random jitter to deterministic jitter; for each of the plurality of values for random jitter, convolving the value for random jitter with the measured value for deterministic jitter and performing a double delta approximation to calculate a plurality of second ratios (ξ dd ) of random jitter to deterministic jitter; performing a double delta approximation on a measured jitter distribution to obtain a ratio (ξ dd meas ) of random jitter to deterministic jitter; and, adjusting the ratio (ξ dd meas ) using a relationship of the plurality of first ratios (ξ ml ) to the plurality of second ratios (ξ dd ) in order to produce a corrected ratio (ξ ml corr ) for allowing more accurate separation of components of random jitter and deterministic jitter.
