Urgent Communication Question

    Urgent....Communication Question

    1. The problem statement, all variables and given/known data

    A 1kHz sinusoidal frequency modulates a carrier at 146.52MHz with a peak deviation of 5kHz.Evaluate the exact magnitude spectra of FM signal if Ec=1. Sketch your result. Using carson's rule, evaluate the approximate bandwidth of the FM signal, and see if it is a resonable number when compared with your spectral plot.

    2. Relevant equations

    FM modulation index = deviation divide by frequency of the intelligence (modulating) signal

    Carson rules approximate equivalent to 2(deviation(max) + frequency of the intelligence (modulating) signal(max) )

    3. The attempt at a solution

    the BW i get is 16kHz ....is that correct?

    Please help me check is that the bandwidth is 16kHz...thanks...cause i not so sure is that correct or not
