2. An angle-modulated signal is given as u(t) =
100cos(1000K*pi*t + 5sin(20*pi*t)).
a. Plot the magnitude spectrum for the frequency range as
follows:
For K even: the frequency range is [1000K -
50,1000K+50].
For K odd: the frequency range is [1000K -
40,1000K+40].
b. Determine the power of the signal in that frequency
range.
c. What is the percentage of the power in question b to the
power of the signal u(t).
Note: K = 12
