Abstract :
This letter shows that the synchronization error resulting from a timing recovery loop, operating on nonsynchronized samples of a noisy sinusoid, contains periodic components. This periodic timing jitter is caused solely by nonideal interpolation between the nonsynchronized signal samples and is absent when using synchronized sampling. The results of our linearized tracking analysis are confirmed by computer simulations
