Hi Ali,
I'm talking about
http://gnuradio.org/doc/doxygen/classgr_1_1analog_1_1frequency__modulator__fc.html
This is the and thus only comprehensive documentation.
But really, all this block does is, like I in text [1] and activecat in
text and code[2] tried to explain,
is increase the phase of i

If you refer to the source code of the frequency_modulator_fc_impl.cc, then
the min and max frequencies could be calculated.
Says,
You still seem to have no real grasp on what the frequency_modulator
block does.
Read my reply, and the documentation to that block again:

Ali,
again: there is no center frequency in a baseband simulation. Your
sawtooth-repeat combination will give you a step signal, where the
amplitude is constant for 500 items. All frequencies that you set are
only used to calculate what will happen in one sample.
The frequency mod is but an input
Correction not 50 Hz but whatever the rate is after interpolation

Another question related to my flowgraph that when i use the' Frequency
Mod' block...then it will take the center frequency as 50Hz(the freq of the
signal coming in)??

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.

Well, when I use the same sensitivity as u, I cant see, but with higher
value u can see.U can use average option but still with that sensitivity u
will not see much.
