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.
