METHOD AND CIRCUIT FOR DEMULTIPLEXING DIGITAL SIGNALS CAPABLE OF ABSORBING DESTUFFING JITTER

摘要

The present invention provides a method and circuit for demultiplexing digital signals which generates no errors even when destuffing jitters are heavy. Buffer memory 2 for smoothing performs smoothing of the jitters digitally which are to be periodically generated in lower order signals demultiplexed from higher order signals by demultiplexing circuit 1. An analog IC performs resmoothing of the lower order signals which have been smoothed by the buffer memory, and thereafter performs digital/analog conversion thereof and outputs the lower order signals which have no jitters through a transformer.
