I'm getting into RF engineering and your videos help me much to understand many of the concepts a lot better!!!! It's all explained so well and clear, thank you so much!

thank you, now it's clearer; I was getting crazy with that indian accent -_- but apart the indian accent "all about electonics" is a great yt channel.

Thank you for the lectures; they are very helpful, thank you. Question: Should Vout be Adm(V2-V1) instead of Adm(V1-V2) shown in the video?

What I don't understand, is that if noise is present in both inputs of the OA, when you subtract them, you should see 0V. So i do not understand why it's amplified.
