Questions

Which syllabus does the Digital Signal Processing 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.

Is MATLAB compulsory?

MATLAB is preferred; Octave or Scilab may be used for practice where MATLAB is not available.
