Hello, i have questions from a book that I'm reading, it's full of interesting problems about Electrical Engineering. For now i want to ask about op-amp offset error. I will post a copy of the problem here. We can talk about it, i have an idea about offset error so i can share it here later...

Hello, I would like to ask if it's possible to send assignments from book that I'm reading: Ten Essential Skills for Electrical EngineersThis book is quite interesting , sometimes i solve its assignments but i find it quite challenging. Can I send regularly and discuss about it? I'm an...

I'm interested in analogue electronics in general. There is a book I liked named: Ten Essential Skills for Electrical Engineers by Barry L. Dorr. I've been reading it, somehow it's quite comprehensive and includes almost everything in clever way. I would be glad to have someone discuss with...

I just have Electronics Engineering diploma. Currenly I'm not involved in any school, actually I'm not from here. I live in Europe but I'm not participating in scientific activities, I'm just working whatever. That's why I decided to write here, perhaps to meet friends and discuss about Electronics.

Hello, I'm just open to new ideas about Electronics. For some reason or another, I loved this community. I want to participate in discussions about Electronics but I want something constructive, new ideas. I'm located in Europe so it would also nice to meet with other members here and share...

By calculating manually with the same steps for h=0.2 (which is quite large as you said) I got y2(1)=2,..(something) I don't remember but i think it's still acceptable for this large assumtption of h, so the guess that y2(0)=1 was not bad I think. Yes and y1(1) is almost 0.5 which ensures that...

I don't think so but why do you ask?

So when i applied your equations I got y1(1)=0 and y2(1)=2 assuming y2(0)=1 for increments h=0.2. Which is quite logical because y1 is strictly decreasing with x and y2 is strictly increasing with x as pasmith said.

No, only numerically.

Thanks but still not clear how to step forward to the other boundary point. We have two equation, i don't know from which one to start and how. What assumptions should be made and what concrete processes? Can you make it a little bit more clear?! Thank you.

Hello, can anyone give me the general instructions of solving shooting method problem: dy1/dx=-y1^2*y2 dy2/dx=y1*y2^2 with the boundary conditions: y1(0)=1, y2(1)=2

OK, thank you again.

But I still don't understand how e^(-j*2*pi/N *2)= e^(j*2*pi/N). Are these two angles identical??

That is a very good and summarized answer. Thank you RUber :)

No i mean for each actual frequency wha are the sampling results for fs=1000 Hz and then for fs=1002 Hz.
