COMMUNICATION SYSTEMS
(Core Subject)
Course Code: 10B11EC514 Semester: 5th Semester, B. Tech
(CSE/IT)
Credits: 4 Contact Hours: L-3, T-1,P-2
Course Objectives1.
To introduce the concept of communication system.
2. To make the students to know the constituents of the communication systems such as transmitter, receiver and
channel with their features.
3.
To enhance the understanding of communication system and device.
Course OutcomesThis course provides the knowledge of analog and digital communication system analysis and design. After study
through lectures and assignments, students will be able to:
1. Formulate and interpret the presentation and processing of signals in communication systems.
2.
Assess and evaluate different analog and digital modulation and demodulation techniques
3. Develop an ability to compare and contrast the strengths and weaknesses of various communication systems.
4. Evaluate the influence of noise on communications signals.
5.
Understand the state-of-art of the communication systems.
