Questions

Which syllabus does this course follow?

It follows the BTEUP (Board of Technical Education, Uttar Pradesh) syllabus of Digital Electronics (Semester 3 / 4). Where your polytechnic follows a different board or a revised syllabus, the centre follows your own syllabus.

Will it help in the semester examination?

Yes. Every unit is covered with solved examples, unit-wise MCQs and previous-year style questions for the BTEUP theory and practical exams.

Is the Digital Electronics Lab covered too?

The lab is a separate course; here every circuit is explained with its truth table so that lab experiments become easy.
