Transmission
Objective: To understand the fundamental components and operation of a telecommunication
system, including signal transmission, modulation, and network structure.
Question:
Problem Statement:
You are tasked with analyzing a basic telecommunication system and describing how
information (voice, data, or video) is transmitted from a source to a destination. Your assignment
involves identifying the key components of a telecommunication system, explaining signal
transmission methods, and exploring the role of modulation in telecommunications.
Requirements:
1. Telecommunication System Components:
o Identify and describe the main components involved in a basic telecommunication
system. Include the following:
▪ Transmitter: Explain its role in signal processing and the conversion of
information to a transmittable signal.
▪ Transmission Medium: Describe different types of transmission media (e.g.,
wired, wireless, optical) and discuss the advantages and disadvantages of each.
▪ Receiver: Explain how the receiver processes the incoming signal and converts it
back into usable information.
2. Signal Transmission:
o Define analog and digital signals, and compare the characteristics of each in the context
of telecommunication.
o Explain the differences between baseband and broadband transmission, and give
examples of each type.
3. Modulation Techniques:
o Research and explain the importance of modulation in telecommunication systems.
Address:
▪ Why modulation is needed for efficient transmission.
▪ The differences between amplitude modulation (AM), frequency modulation
(FM), and phase modulation (PM).
o Choose one modulation technique and describe a real-world application of this
technique in telecom systems.
4. Noise and Interference:
o Define noise and interference in telecommunication systems.
o Describe the common types of noise (e.g., thermal noise, intermodulation, crosstalk)
and their effects on signal quality.
o Discuss methods used to mitigate the effects of noise on signal transmission.
5. Basic Network Structure:
o Describe the difference between circuit-switched and packet-switched networks,
providing examples of each.
o Explain how data is routed in a packet-switched network and the advantages of packet
switching over circuit switching in modern telecom systems.
Example Outline for Submission:
1. Telecommunication System Components:
o Explanation of transmitter, transmission medium, and receiver functions.
2. Signal Transmission:
o Comparison of analog vs. digital signals, baseband vs. broadband transmission.
3. Modulation Techniques:
o Overview of AM, FM, PM, and a real-world application of one chosen technique.
4. Noise and Interference:
o Description of noise types and methods of noise reduction.
5. Basic Network Structure:
o Explanation of circuit-switched vs. packet-switched networks.
