Coding and decoding of clock synchronization in digital multiplexing system

Digital multiplexing is the basis of high-speed broad band digital communication network, whose theory kernel is processing and transmitting the clock synchronization. The transmission of clock synchronization was not understood systematically and thoroughly before, and it is limited to only analyzing the jitter of justification. This paper interprets the process of clock synchronization in multiplexing system from quantizing and coding the information of clock synchronization (interprets justification from T Delta-SigmaM), and interprets the jitter of justification from quantization error. According to the theoretic model, decreasing the jitter caused by justification is namely decreasing the quantization error, because the jitter is caused by the quantization error of the information of clock synchronization.
