Estimating Bandwidth of Phase Modulated Signal Using Taylor Series

[QUOTE="ace1719, post: 4713478, member: 471872"] [h2]Homework Statement [/h2] Consider the PM (phase modulated) signal, s(t) = Acos(wt+x(t)) where x(t) is the information bearing signal. Assume that |x(t)|< y, which is not necessarily small. Using Taylor's series expansion, derive an estimate for the bandwidth of the PM signal s(t). [h2]Homework Equations[/h2] [h2]The Attempt at a Solution[/h2] I was able to get the Taylor series expansion of s(t). I'm guessing the relevant part of the expansion is (wt+x(t))^2k. At this point I would guess that you'd want to substitute the maximum value of x(t) in - which is y - to get, (wt+y)^2k. If you couldn't tell, this required a lot of guess work, but I'm lost as to what to do at this point. I'll thank you for your help in advance. [/QUOTE]
