Questions
Which syllabus is followed?
The current AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus of Communication Engineering Lab (Electronics & Communication Engineering, Semester 4). If your university or college follows a different syllabus, the centre teaches from your own university syllabus.
How is the lab assessed?
By the experiment performed, readings or output, the practical record file and a viva voce, as in the AKTU internal and external lab examination.
Do I need to maintain a record file?
Yes. The centre helps you write each experiment with aim, apparatus, theory, circuit diagram, observations, calculations, result and precautions.
