    I am working on a problem for school and am having trouble understanding it. It asks for two things the frequency deviation and max frequency deviation. We are given that kf = 30Hz/V and I am pretty sure that the max frequency deviation is the max message signal times kf which would be 240Hz since this is an FM signal. I am a little confused about just frequency deviation and the difference between the two. Any help would be appreciated or just some clarification.

    Start by tracking the units.
    1. 2 is dimensionless
    2. pi is dimensionless
    3. kf is Hz./Volt or (1 / (Volt⋅sec))
    4. the integral is Volt⋅sec
    Does that help?
