摘要
在数字信号处理理论的基础上,利用MATLAB中的GUI工具箱,设计了一个通过可视化界面交互实现的DTMF信号合成和检测系统,并给出了DTMF信号的产生与检测方案。实验结果表明,该系统性能较好,可帮助初学者理解电话拨号和解码过程。
Based on the theory of digital signal processing,this paper designs a DTMF signal synthesis and detection system through visual interface interaction by using GUI toolbox in MATLAB,and gives the generation and detection scheme of DTMF signal.The experimental results show that the performance of the system is good,and it can help beginners to understand the process of telephone dialing and decoding.
