Summary: This article presents a low complexity dual tone multiple frequency (DTMF) signal detectort hat meets they ternation a Telecommunication Union (ITU) Q.24 DTMF standard while implemented on a general purpose Digital Signal Processor(DSP). The proposed DTMF detectoris based on the Goertzel algorithms and is well suited for a multichannel implementation. Our solution offers increased accuracy and noise margins, while preserving the inherited advantages of the Goertzel algorithm (less memory requirements and computational complexity).

O detector DTMF proposto é baseado no algoritmo de Goertzel e bem adequado para implementação multicanal. Nossa solução oferece elevada precisão e margens de ruído, enquanto preservada vantagem inerente do algoritmo de Goertzel(menor necessidade de memóriae baixa complexidade computacional).Universidade de Fortaleza - Unifor2009-08-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.unifor.br/tec/article/view/184Revista Tecnologia; v. 23 n. 1 (2002)2318-07300101-8191reponame:Revista Tecnologia (Fortaleza.
