eq 4.32 is given below

4.13 Assume that the bandwidth of the message signal of Figure 4.31 is band-limited to the third harmonic of its fundamental frequency, and that frequency modulation with a frequency deviation constant of k, = 10n is performed. (a) Find the frequency deviation of the FM signal. (b) Find the phase deviation constant such that if phase modulation is performed, the PM signal will have the same bandwidth as the FM signal. (c) Find the bandwidth of the FM signal using Carson's rule. (d) Find the bandwidth of the FM signal using the conservative rule of Eq. (4.32).
