DTMF Signal Generator and Detector Based on Virtual Instruments and PC Sound Card

摘要：

This paper implements DTMF signal generator and detector by a virtual instrument approach. Firstly, the DTMF system is introduced, and the key points in virtual instrument implementation is discussed. Then the DTMF system is built by LabVIEW software and PC sound card hardware. The front panels and block diagrams of the generator and detector VI programs are explained. The system uses event structure and math script node. The system runs well and fulfils its goal.
