Farhan Kaif, i am using these notes to cover IR. Thank you so much for sharing them.
However, I find it too much summarized. References are not given adequately. The author has stated only in the beginning which books are used. But still some confusion persists.
I can't easily understand the various concepts by reading only these notes. can you help me?
