Abstract

A decoding means of IRIG-B(DC) time code is proposed on the basis of analyzing the wave characteristics of IRIG-B(DC)code.This design is made up of peripheral circuits and FPGA to implement decoding of IRIG-B(DC) code and 1 pps signal output and real-time time display and serial asynchronous communication.Compared with traditional methods,it has lots of advantages such as smaller size,lower cost and more reliable stability,and can replace the main functions of traditional B-code device.
