Question 1
a) i. Discuss why the carrier waves are of higher frequency
compared to modulating signal and explain in six different ways our
inclusion of modulation in communication system.
ii. By a suitable graphical representation sketch signal
voltage (V) against period (t) of an FM System at t ranges from
1second to 12 seconds. Taken magnitude of signal voltage to be
10V,
You are required to show work [10 Marks] EV
b) A similar graphical sketch is demanded by a world class
telecommunication company to enable analyze their transmission
network. You are to appreciate both the signal voltage and the
carrier deviation by 55%, to help achieve this feat. All relevant
steps are needed. [6 Marks] CR
c) Perform a comprehensive analysis on the two solutions in a
and b. Discuss why an operator will use FM and AM system at the
same time [4 Marks]
