Stochastic processes and linear combinations of periodic clock changes

Stochastic processes subjected to a periodic clock change function will have weighted versions of its power spectrum reproduced at integer multiples of the jitter frequency. It has been shown that the original process may, in theory, be reconstructed without error by a suitable choice of correction filter. We extend the results presented by Lacaze and Aakvaag (see ISIT'94) to the general case where the resulting process is a linear combination of N clock change functions.
