基于MCU的新型音频信号传输实验仪的设计与实现

摘要

A method is proposed to improve the audio signal optical fiber transmission for overcoming shortcomings in its usage. Based on the method, the MCU chip is used as the master chip, and the traditional digital potentiometer is replaced with digital potentiometer so it can completely realize digital control and measurement. At present, the device has been completed and the experiment result shows that the system structure is rational. In addition, it has good operating performance, accurate measurement parameters, high reliability and stability, and it can satisfy the requirements of high-precision and multifunction control.%针对现有型号音频信号光纤传输实验仪在使用中存在的不足问题，提出了改进的设计方法。以MCU为主控芯片，利用数字电位器取代传统电位器，实现全数字化控制与测量。目前该装置已研制完成，测试结果表明：改进后的新型仪器架构合理，操作性能良好，测量参数准确，可靠性高，稳定性强，能够实现实验仪的多功能化及高精度要求。
