I was experimenting with this the other day. I used
the wide band FM modulator instead, since the
deviation can be set. Here's the flow graph.

The test audio files. sine01.wav is 0.1 Hz and
sine15k.wav is 15000 Hz.

Some C code to generate audio files at other frequencies.

Hi,
I have made the flowgraph as attached..It is showing the modulation in scope but in fft block it's continuously changing so I am still unable to find out that what are the max and min frequencies??I know how to find that in theory but i want to prove it from my results..
