सवाल

Which syllabus does the Principles of Electronic Communication course follow?

It follows the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus for Principles of Electronic Communication (Electronics Engineering, Semester 3). If your own board's or institute's syllabus differs, the centre follows your own syllabus.

Will this help in the semester examination?

Yes. Teaching is unit-wise as per the BTEUP scheme, with previous-year question practice, MCQ tests and doubt sessions before the semester exam.

Are numericals on AM and FM covered?

Yes. Modulation index, power, bandwidth, image frequency and antenna length problems are practised.
