सवाल
Which syllabus does the Digital Communication Lab course follow?
It follows the current AKTU B.Tech (ECE) scheme, Semester 6. If your university or college uses a different scheme, the centre follows your own university syllabus.
Do you cover numericals and previous year questions?
Yes. Each unit is taught with solved numericals and AKTU previous-year questions.
What is marked in the practical exam?
Performing one experiment, the waveforms and readings, the lab record and the viva.
