Second Harmincs in speech signal - manoj garg - Jul 23 4:48:00 2002

Hello friends, I wanted to know that what is the ratio of second harmonic energy to the fundamental frequency energy in the speech signal. Actually i am implementing a DTMF detector and to discriminate the DTMF signal from the speech i have to put this check. thanking you, manoj |
