Design of Multiple DTMF Signal's Transceiver In E1
Zhengyu Chen, YE Qing-di · Journal of Jinling Institute of Technology · 2005
Abstrcat This article introduces a successful scheme through which we can generate and detect the DTMF signals in E1.The paper firstly describes the fundamental principle of DTMF signal's detecting and generating and improves the algorithm. Then it provides the hardware circuit of the transceiver composed of fixed point DSP-TMS320F206 and XC95108 CPLD chips, it also gives the scheme of software design. Finally it makes the analysis of transceiver performance.
