\text { Given } f_{c}=200 \mathrm{~Hz}, A_{c}=1, k_{f}=1, m(t)=5 \cos (20 \pi t) Determine the approximate bandwidth of the WBFM wave, using Carson's rule. Show S(f) within the transmission bandwidth. (Hint: find Jn (B) using Matlab) Plot the spectrum of WBFM signal using Matlab. Clearly mark the transmission BW.
