Question

Answer question 7 showing fully all the steps. Solution should be simplified and easy to understand as much as possible!

Fm = 4000 Hz
=> Signal bandwidth = 2 x 4000 Hz = 8000 Hz
STUDY QUESTIONS:
* a) Name the components of a communication system and state the role of each component.
D) Distinguish between the following communication terms.
i) Encoding and decoding
ii) Modulation and demodulation
2) Up to the late 1990s in Cameroon the telephone was fixed. State and explain any two ways
in which the advent of the mobile phone has led to improvement in communication.
3) Why is the radio receiver circuit, commonly called a resonant circuit?
4) Give three plausible reasons why a mobile phone user or subscriber may be unable to reach
another mobile phone subscriber.
5) a) A radio station is broadcasting on FM using carrier waves of frequency 89.7 MHz. To
what value must the variable capacitor of a receiver be set to tune to the station if the
receiver has a fixed inductor of inductance 1.24x102 mH.
b) What specific roles do the capacitor and inductor play for reception of information by
radio to be possible?
6) Why may it be impossible for two radio stations to broadcast on the same frequency in
Yaounde using FM but possible for one in Yaounde and the other in Garoua to use the same
frequency on the FM?
7) Despite the multiple advantages of the mobile phone there are some drawbacks. State and
explain any two drawbacks of the mobile phone.
