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.

  1. What book/books would be best for preparation of this paper?

    1. I couldn’t find a book that had everything in the FYUP Syllabus. Instead I used different books for different topics. Some of those were: Floyd Electronic Devices and Circuits, Bolyestead, and a few more but I dont remember their names at the moment. I used the resources found on the Internet for a lot of topics.

  2. sem v physics of devices & physics book , advanced mathematical physics book hame chaye kaha se milega eya books Mai book ke liye Bokaro all pustakalay se puchye lakin kahi se nhi Mila kripa karke es book ko Mera mail per pustakalay ka address bhaje

  3. sem v physics of devices & instruments & advanced mathematical physics book mujhe chahey
