Communication System Laboratory

Communication system laboratory is employed for the under graduate students of the institute. The under graduate students of the department of Electronics & Communication Engineering utilize the laboratory for their Analog Communication Lab (EC 591) in 5th semester & Digital Communication Lab (EC 691) in 6th semester study of  the course. This laboratory also provide the facilities for the under graduate  students of department of Computer Science & Engineering  and department of Information Technology of the institute for performing laboratory work in Communication engineering & coding theory  Lab(CS 491)  in 4th semester of their study. This laboratory also provide the additional facilities to the interested under graduate and post graduate students of the department for performing their project work in the domain of communication systems.
