MSBTE K Scheme – 313326 Principles of Electronic
Communication Notes PDF
The Principles
of Electronic Communication under the MSBTE K Scheme is a
fundamental subject for Diploma in Electronics, Telecommunication, and
Electrical Engineering students. It focuses on the theory, design, and
application of electronic communication systems.
Electronic
communication plays a critical role in modern society, enabling voice,
data, and video transmission over short and long distances. This subject
equips students with knowledge about signals, modulation techniques,
transmission media, antennas, and communication protocols.
Importance of Principles of Electronic Communication
- Provides the foundation for telecommunication
and networking systems.
- Explains signal transmission, reception, and
processing.
- Essential for designing communication devices
like radios, mobile phones, and satellite systems.
- Enables understanding of analog and digital
communication techniques.
- Helps in career preparation for
telecommunications, IT, and electronics industries.
- Supports advanced subjects like Wireless
Communication, Data Communication, and Networking.
MSBTE K Scheme Syllabus Overview – Principles of
Electronic Communication
The syllabus is structured to
cover both theoretical concepts and practical applications of
communication systems.
Unit 1: Introduction to
Communication Systems
- Basic elements of a communication system:
transmitter, channel, receiver, noise.
- Types of communication: analog vs digital,
point-to-point vs broadcast.
- Advantages and limitations of electronic
communication.
Unit 2: Signals and
Transmission
- Analog and digital signals.
- Time and frequency domain representation of
signals.
- Signal attenuation, distortion, and noise.
- Transmission media: guided (twisted pair, coaxial
cable, optical fiber) and unguided (radio waves, microwaves, infrared).
Unit 3: Modulation Techniques
- Need for modulation in communication.
- Analog modulation: Amplitude Modulation (AM),
Frequency Modulation (FM), Phase Modulation (PM).
- Digital modulation: ASK, FSK, PSK, QAM.
- Applications of each modulation technique in
real-world systems.
Unit 4: Demodulation and Receivers
- Demodulation techniques for AM, FM, and PM signals.
- Superheterodyne receiver principle.
- Concepts of sensitivity, selectivity, and fidelity.
- Noise effects on communication systems and
signal-to-noise ratio (SNR).
Unit 5: Antennas and Wave
Propagation
- Types of antennas: dipole, loop, horn, Yagi-Uda.
- Radiation pattern, gain, and polarization.
- Basics of wave propagation: ground, sky, and space
wave.
- Line-of-sight and satellite communication
principles.
Unit 6: Modern Trends in
Electronic Communication
- Digital communication systems and modulation.
- Optical fiber communication: principle, advantages,
applications.
- Satellite communication systems: uplink, downlink,
transponders.
- Mobile communication systems: 4G, 5G, and IoT
applications.
- Introduction to wireless communication and smart
communication systems.
Practical Applications of Electronic Communication
- Television and Radio Broadcasting →
Transmitting audio and video signals.
- Mobile and Satellite Communication →
Internet, voice calls, GPS systems.
- Optical Fiber Networks → High-speed
broadband and data transfer.
- Wi-Fi and Bluetooth Devices → Short-range
digital communication.
- Remote Sensing and Radar → Navigation,
weather monitoring, and defense applications.
- Industrial Communication → SCADA and
automation systems.
Real-Life Industry Examples
- BSNL, Jio, Airtel → Use of analog and
digital communication for mobile and broadband services.
- Doordarshan and All India Radio →
Broadcasting using AM, FM, and digital signals.
- Indian Space Research Organization (ISRO) →
Satellite communication and remote sensing.
- Optical Fiber Networks → Reliance Jio and
BharatNet projects for high-speed internet.
- Wi-Fi and IoT Devices → Smart home
automation and industrial communication systems.
