| Abstract: | Intelligent transfer system has to multiply connect operations such as video,audio,Ethernet and data traffic.An audio communication system based on CMX649,a programmable voice decode chip,was designed for low-speed transmission.Its system design and software design method,together with Modelsim simulation waveform,were also given.Testing results show that the system has good audio communication effect.It′s beneficial to design of fibre-optic transmission system(FOTS) in low-speed multiple connections. |
