基于FPGA的DTMF信号检测器硬件设计与实现

A case Study on Hardware Architecture and FPGA Implementation of DTMF Detect

论文在研究Goertzel算法的基础上采用了基于硬件的实现方法完成了DTMF信号检测。基于Verilog HDL语言实现了DTMF信号检测的RTL设计,并完成了功能验证,然后基于Altera的DE2-70开发板,完成了FPGA硬件设计,并在开发板上实现了DTMF信号的检测。

This paper presents the hardware implementation of DTMF detect. Based on the Goertzel algorithm, the RTL design in Verilog HDL and verification was accomplished, then FPGA was implemented based on the demo board of DE2-70 from ALTEKA.
