Abstract

This paper discusses the FPGA implementation of modified Goertzel Algorithm for the application of DTMF signal detection, which is as effective as that of normal Goertzel Algorithm yet is more resources saved than that of normal Goertzel Algorithm. Detail algorithm simulation and algorithm FPGA implementation are given in the paper.
