सवाल

Which syllabus is followed?

The current AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus of Digital Signal Processing (Electronics & Communication Engineering, Semester 5). 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.
