【摘要】 选用非编程芯片设计了一种立体声数字音频信号光纤传输实验系统。系统由信号发送端机、光纤传输链路、信号接收端机组成,并利用2个不同波长的光信号作为载波分别传输左右声道的音频信号。仿真结果表明,系统可实现立体声音频信号的稳定传输。系统的全非编程芯片设计结构,使其各部分电路功能明确和易于更换,适合用于实验教学演示,能让学生更直观地理解数据如何组帧、传输等过程,具有较强的应用价值。更多还原

【Abstract】 A stereo digital audio signal optical transmission experiment system using non- programmed chip is designed and studied.The system consists of transmitting terminal,fiber optic link as well as receiving terminal,and the two sound tracks of stereo audio signal are transmitted separately by using two light signals which have different wavelengths.The simulation results show that the system can realize the stable transmission of stereo audio signal.Due to the design structural of the non-programmed chip,the various parts of the circuit have clear function and are easy to be replaced.When the system is used for experimental teaching demonstration,it can enable the students to have a more intuitive understanding of the process of data framing and transmitting.Accordingly,the system has a strong application value.更多还原
