Best of Luck for Your Exams

Dear Participants,

I hope  you enjoyed  being a part of the NPTEL MOOC on Principles of Signals and Systems (PoSas)and found it to be a learning experience.  I really enjoyed teaching the course and it was a wonderful experience. The certification exam of the course will be held on 28 and 29 April (Afternoon session 2 to 5 pm) . I wish you all the best for the same. Following are the details regarding question paper format and final score.

Format of question paper:

Total Questions = 50
Marking Scheme: 2 Marks for each correct answer. NO Negative marking.
a). 10 Questions - Recall Type 
b). 15 Questions - From example problems in lectures and assignment problems 
c).  25 Questions - Open. 

Formula to compute final score:
Final score = 25% Assignment score + 75% Exam score
Assignment score is calculated as the average score of  the best 8 out of 12 assignments.

Note

Scientific calculators can be carried by the candidates into the exam hall. You will be given rough paper and pencil for working out the problems (which you will have to return after the exam).
Please  do not hesitate to contact TAs of the course for any additional clarification. I hope to see you in large numbers for the certification exam and participation in our future courses.

It has been a great pleasure and I look forward to continued interaction with all of you. All the best and please let us know your feedback.

Regards,

Prof. Aditya K. Jagannatham

Mistakes in Assignment 6 question 2

Dear Participants,

In Assignment 6 question 2 : In all the options it should
$sin(\Omega_0)$ instead of $sin(\Omega_0 n)$ and
$cos(\Omega_0)$ instead of $cos(\Omega_0 n)$


Updated options are :
a)$\frac{rsin(\Omega_0)z}{z^2 -2rcos(\Omega_0)z + r^2}$
b)$\frac{sin(\Omega_0)}{r^2 z^2 -2rcos(\Omega_0)z + 1}$
c)$\frac{z^2 -rsin(\Omega_0)z}{z^2 -2rcos(\Omega_0)z + r^2}$
d)$\frac{rsin(\Omega_0)z}{z^2 -2rsin(\Omega_0)z + r^2}$

Regarding Duplication of Questions

Dear Participants,
As you would have seen we have marked many questions on discussion forum as duplicate.
We don't mind answering the same question repeatedly it. We really are OK with it and understand that it at times happen unintentionally and most of the times questions are slightly different.
Kindly do not take it personnally and we don't mark it as duplicate to show any sort of offense.
It is done just to save our time and space on the database[to avoid uploading same files again and again].

We highly encourage you to ask questions on the Discussion forum.
We also appreciate that some of you [Garman Dale Mv Dk Laxman Chaudhary Raghunath Reddy, Kartik and Sathish kanakaiah] reply to queries asked by other participants.
Thanks

This has been corrected in the lecture notes and also pointed to in subsequent video lectures. We apologize for this inaccuracy.
