Questions
Which syllabus does the Digital Communication Systems course follow?
It follows the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus for Digital Communication Systems (Electronics Engineering, Semester 4). 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 included?
Yes. Nyquist rate, PCM bit rate, baud rate, entropy and channel capacity problems are practised.
