FAQs on Introduction: Communication System - GATE Notes & Videos for Electrical Engineering - Electrical Engineering (EE)

1. What is a communication system?
Ans. A communication system is a set of devices and networks that allow the transmission and reception of information between two or more parties. It includes various components such as transmitters, receivers, channels, and protocols to enable the exchange of data or messages.
2. How does a communication system work?
Ans. A communication system works by converting the information or message into a suitable format for transmission, which is then sent through a physical medium or a wireless channel. The transmitter encodes the message, and the receiver decodes it to retrieve the original information. The process involves modulation, demodulation, encoding, decoding, and error correction techniques.
3. What are the different types of communication systems?
Ans. There are various types of communication systems, including wired systems such as telephone networks and Ethernet, wireless systems like cellular networks and Wi-Fi, satellite communication systems, optical communication systems using fiber optics, and even computer networks like the internet.
4. How do communication systems ensure reliability and quality?
Ans. Communication systems ensure reliability and quality through various mechanisms. Error detection and correction techniques are employed to minimize transmission errors and ensure data integrity. Quality of Service (QoS) mechanisms prioritize certain types of data, ensuring smooth transmission for critical applications. Redundancy and backup systems are also implemented to ensure reliability in case of failures.
5. What are the advantages of modern communication systems?
Ans. Modern communication systems offer numerous advantages, including faster and more efficient transmission of information, wider coverage areas, increased capacity to handle multiple users simultaneously, improved audio and video quality, and greater flexibility in terms of mobility and accessibility. These systems have revolutionized global communication, enabling seamless connectivity and collaboration across vast distances.
