运用FFT技术来综合和分析电话拨号的过程,matlab来分解了这一过程,希望能提供帮助( TOUCHTONE Use FFT to synthesize and analyze telephone dialing
The dual tone multi-frequency (DTMF) standard specifies that the tone
generated by a button on a telephone key pad is the sum of two sinusoids,
with frequencies determined by the button s row and column.
The dial pad on the upper left allows you to select buttons and generate
the corresponding tones.
The signal plotted on the upper right is a recording of the FAX number
for the MathWorks being dialed. You can replay the entire signal, or
select individual segments. The power plot is the magnitude of the FFT
of the signal being played. What is the MathWorks FAX number?)
