Hello,
I can't work out the formula above. I tried a lot but don't get it.
I found this lecture:
http://www.ece.ucsb.edu/yuegroup/Teaching/ECE219Winter2013/Lecture%20slides%20an...At the page 9, the professor derived the formula for the same problem. I understand the lecture perfectly. However, as I checked two formulas (the first one is that in original post and the second is the one in the lecture), they are NOT the same. I am sure that the formula in the lecture is correct but can't tell if the one above also right.
I also checked both of them as delta δ =0 and they are different!
The only error I can see in the original is Rs^2 - sLs^2. It should be Rs^2 - (sLs)^2.
If you have derived that formula, please tell me how to do that. Thanks.
