FAQs on Principle of Communication Engineering Question Paper, BE Electronics & Communication Engg. (ECE) - Electronics and Communication Engineering (ECE)

1. What is the principle of communication engineering?
Ans. The principle of communication engineering involves the study and application of techniques and technologies used for transmitting, receiving, and processing information through various communication systems. It focuses on the principles of modulation, demodulation, encoding, decoding, transmission media, and signal processing to ensure efficient and reliable communication.
2. What are the key topics covered in the Communication Engineering exam?
Ans. The Communication Engineering exam typically covers topics such as analog and digital communication systems, modulation techniques, noise and interference, information theory, communication channels, coding and decoding techniques, multiplexing, transmission lines, antennas, and wireless communication systems.
3. How does modulation work in communication engineering?
Ans. Modulation is the process of modifying the characteristics of a carrier signal to transmit information. In communication engineering, modulation techniques such as amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM) are used. These techniques vary the amplitude, frequency, or phase of the carrier signal in accordance with the input signal to carry the desired information.
4. What is the role of coding and decoding techniques in communication engineering?
Ans. Coding and decoding techniques play a crucial role in communication engineering to ensure reliable transmission and reception of information. Coding involves the conversion of the information signal into a format suitable for transmission, while decoding involves the extraction of the original information from the received signal. Techniques like error detection and correction codes, such as Hamming codes and Reed-Solomon codes, are used to minimize errors and ensure accurate communication.
5. What are the different types of transmission media used in communication engineering?
Ans. Communication engineering utilizes various types of transmission media to establish communication channels. Some commonly used transmission media include guided media such as twisted pair cables, coaxial cables, and optical fibers, which provide a physical path for signal transmission. Wireless media, such as radio waves and microwaves, are also used for wireless communication. Each type of transmission media has its own advantages and limitations in terms of bandwidth, distance coverage, and susceptibility to interference.
