Problem 3: An FM signal s(t) = 100 cos(2л f¸t+40 √ m(t)dt),With m(t) =| 10】 40′ [10Σ II(ª¯”) –10 Σ II 00 00 -4n. t-4n-2 ПI (a) (b) 2 12--00 Determine the peak-frequency deviation and the peak-phase deviation. Sketch m(t) and the instantaneous frequency as a function of time, given f. =1000Hz. 2 ³¹)]u(t). =-00

From Carson's rule, determine the approximate bandwidth of the FM signal.
