Re: [Discuss-gnuradio] FM Modulation problem/question

Thank you, Kevin. That is reassuring. My next question then, is since the deviation is affected by both amplitude and frequency, how would you recommend I empirically determine/set a peak deviation of 2400Hz for 1200Hz baseband? Is this experiment not possible to visualize/determine on a

[Discuss-gnuradio] FM Modulation problem/question

I am trying to wrap my head around FM modulation, and have setup some experiments in GNU Radio to help, but they have only raised more questions. I am trying to achieve a peak deviation of 2400Hz using a baseband signal of 1200Hz. In my flowgraph [here](http://imgur.com/5pzSnsq), and [here](
