Abstract: T he typ ical D TM F signal detection system is designed and simu lated u sing M A TLAB L ink fo r
CCS D evelopm en t Too ls in th is paper. T he step s and resu lts of design ing D SP system are also in troduced
in th is paper. D TM F signal detection is realized u sing Goertzel arithm etic, and the w ho le p rocess of
D TM F signal detection is ob served w ith M A TLAB L ink fo S. T h is detection system can be u sed in the
comp rehen sive speciality experimen t fo r the undergraduate studen ts of electron ic and info rm ation m ajor.
