The paper was held on 5th December 2015.
This particular paper was taught for the first time only to the erstwhile FYUP students.
I kinda liked the subject but couldn’t answer all the questions in the exam as it was very tough.
Most of the questions seemed out of syllabus.
I can only hope for lenient marking.
This questions from this paper can also be used to prepare for the subject, Analog Devices, Instrumentation as well as Communication, as it was a hybrid of all the three.
Don’t forget to share it with your friends on facebook.
If you have a query, just comment in the section below and I will get back to you, ASAP.
