| Abstract: | Based on the PGC demodulation, a novel AGC circuit combined with the signal processing of PGC demodulation is analyzed, and an emulator is designed. The results show that the AGC circuil plays important role in the output amplitude stabilization of fiber-optic interferometen hydrophone. |
