Problem 1: An angle modulated waveform is given as s(t)=A_cos (1000 at +8071 +3204) where 0.=10001 , max|m(t)=3 , and m(t)=0,+<0. In a previous ICE, we determined that if the signal is phase modulated (PM), the phase sensitivity is k= 4001 - 133.31 , the message signal is m(t)=1 12 and the frequency deviation is Am=-80 tn 5-55.51 . Similarly, if the signal is frequency modulated (FM), the frequency sensitivity is kr , the message signal is m(t)==3(3), and the frequency deviation is Aw=- 80 In () – 55.51 (a) What additional information would you need in order to solve for the bandwidth for the FM and PM signals? (b) How would you determine the additional information needed? You do not need to solve for the information, but do need to explain how you would solve for it. (c) Do you expect the bandwidth to be different for the FM and PM signal? Why or why not?
