An angle modulated signal with carrier frequency w = 2 x 10 is given by PEM(t) = 2 cos (we t - 20 cos (1000 -t)- 10 cos(2000-t a) (6 points) Find the power of the modulated signal. b) (6 points) If this an FM signal with k, = 20000*. find m(t). c) (4 points) Find the frequency deviation Af. Hint: The maximum of sin a + sin 2r is 1.76 and NOT 2. d) (4 points) Use the Carson's rule, i.e., BW= 2(B+AJ) to estimate the bandwidth of PEM(1) in Hz.
