Questions
Which syllabus is followed?
The current AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus of Digital Communication (Electronics & Communication Engineering, Semester 6). If your university or college follows a different syllabus, the centre teaches from your own university syllabus.
How is the subject examined?
AKTU assesses it through sessional tests, assignments and attendance, and an end-semester university examination; the centre covers every unit with theory, derivations and numericals.
Are previous-year questions practised?
Yes. Unit-wise AKTU previous-year questions, short-answer questions and the test series are solved in class.
