Hello,
I already searched a lot, but I couldn't find anything useful for me, so here are a few things I would like to know. It would also be nice, if you could just lead me to some references, where I find the solutions by myself.
How does the deviation in FM limit the demodulation? Suppose I have an FM-signal with f_c=100kHz, f_m=3kHz and a deviation of 3Hz leading in an modulation index of m_f=0.1% what can I say about the demodulated signal? I could not find anything about that, because apparently the deviation is usually much bigger than the message signal (dev=75kHz and f_m=15kHz in FM radio broadcasting)
