OP warned about not using homework template
i am trying to figure out digits in a dtmf signal using MATLAB with the fft command however i not sure how to figure out what digit is being pressed.
I am doing this
stem(abs(signal)) and get a plot with several digits pressed but not sure how to figure out which are pressed, any help would be appreciated
