| Abstract: | The audio signal digital communication device design process is introduced.The experiment device is controlled by FPGA and transferred by optical,which explains that audio signal can be conveyed after digitization.Also,the function and the realization of each module circuit have been stated.The device is designed by building blocks,making it flexible and structuring to realize.The circuit is designed and finished in Altium Designer and Protel99,which also has been programmed with VerilogHDL language and simulated in Quartus Ⅱ.The set has been realized and can send or receive audio signal successfully.Proved to meet requirements raised by designer. |
