Hello everyone! It seems to me that there are many ways of calculating SNR depending on the type of signal and the nature of problems. I was able to get a decent amount of information for electrical signals but couldn't find resources which discuss the topic in a more generalized manner. I was...

This was the sort of answer I was looking for. I guess I generalised the question a lot. Thank you for your inputs.

Thanks!

No, I don't. Came to know about it for the first time.

Seems like a good book to me. In case you haven't gone through these reviews, here are the links: http://press.princeton.edu/titles/9771.html

Sure thing. Thanks!

Okay. Thanks for the input. Guess I'll face it over again. The last time I read it was a few months ago and I was entirely new to solid state physics at that time. Maybe this time I'll find the book more helpful and fun.

So I'm fairly new to them and I was wondering about the reasons it is used so extensively. It'd be great to have a discussion on its significance in various applications. When exactly did people start using these diagrams? How is it used in various parts of physics. What all information can it...

I have that book but it seems a bit hard to me at the moment. Also I wanted to look for something which is oriented more to the optical side as well.

So is it safe for me to assume that I probably won't have to deal with quantum electrodynamics if I am dealing with conventional electronic devices such as LEDs and HEMTs?

No it doesn't. It says "for real lens this must be corrected by the numerical aperture.'

So from what I seem to understand up until now, Maxwell's equations usually work while assuming that the fields are continuous and smooth instead of the actual complexity at the atomic scale. However, as we move more and more towards the microscopic realm, a point comes when we cannot ignore...

I understand equation 1.2. What I don't understand is the reason why the author substituted k into Δk.

Here's the screenshot of the text if the google link doesn't work.

So I was reading THIS book on nano optics. It says that the maximum possible spread in the wavevector component k(The spread can occur for instance when the light field converges towards a focus, e.g. behind a lens.) is the total length of the free space wavevector k=2π/λ. Can anyone please...
