| Abstract: | Due to a strong anti-interference ability and faster transmission speed,DTMF has been widely used in a touch-tone phone systems and interactive control system.Such as voice mail,telephone banking and ATM terminals.Therefore it is critical to detect it correctly.The principle of Goertzel algorithm for DTMF tone detection as well as how to choose the main parameters are discussed in detail,focusing on the demonstration of the parameter N optimization.Simulation environment of this algorithm is done in MATLAB ... |
