摘要：

In　this　article,　PGC　arithmetic　at　length　was　discussed　and　then　the　hardware　system　basing　on　PGC　technology　was　designed.　The　system　has　been　applied　for　a　new　pipeline　leakage　detection　system　based　on　Sagnac　interferometer　to　demodulate　interference　signal　phase.　It　is　proved　that　the　circuit　can　demodulate　leakage　signal　effectively,　and　leaking　point　is　located　accurately.
