Q. Suppose that you have an angle modulaton system with an input signal £01) s wiangle wave of fundamental frequency 5 kiz and its most power is concentrated in the frst third harmonics, the masimum and minimu voltage ae | and -1 espectively. where one period equation of theinput s o[BIl 0

Q. Suppose that you have an angle modulation system with an input signal
x) as a triangle wave of fundamental frequency 5 kHz and its most
power is concentrated in the first third harmonics, the maximum and
minimum voltage are I and -1, respectively, where one period equation
of the input is
x(t) = {2. 10°t -1 O<t<i/2
{-2. 10*t +3 T/2<t<T
If carrier frequency f. = 10° Hz, Kf = 2000m, and Kp = T. Find the
following:
1-What is the third harmonic frequency of the input signal?
2- Sketch the waveform of the input signal in the time domain.
3- Find the frequency deviation in case of FM and PM modulation.
4-What is the minimum and maximum frequency in the modulated
signal for FM and PM?
S-Estimate the bandwidth of the modulated signal for FM and PM.
6-Is the modulated FM signal is narow band or wideband? Why?
7-Sketch the waveform of the modulated signal for FM and PM.
8- How can you generate FM for this system using indirect method?
Suggest a method for that and discuss the advantages and
disadvantages of your suggestion.
9-Propose any receiver (demodulator) system to receive the modulated
signal in case of FM. [(Hint: your proposed system consists only a block
diagram and the required equations].
