Jitter reducing apparatus using digital modulation technique

摘要

A jitter reducing apparatus using a digital modulation technique includes: an elastic store storing data flowed in from an SDH network; a pattern generator controlling a data read speed so the elastic store maintains a constant data storing amount; a modulation sequencer generating a digital signal wave having a constant period and amplitude; and a phase level detector controlling the pattern generator using the digital signal wave of the modulation sequencer.
