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]

This question relates to standing waves. A) Does a closed pipe have a higher or lower fundamental frequency than an open pipe of the same length? B) If the length of an open tube is 0.8 m, experimentally find the: fundamental frequency and the frequencies of the third and fifth harmonic. C) We have only addressed the variables of length, wave speed, harmonic number and frequency. These seem to be adequate to fully describe the frequency of a standing wave....
