By dividing the interval 30 - 39.6 from 26.4 - 39.6.

Given the upper data, if the nominal value for capacitance is 33nF and tolerance of 20%, then values can range between 26.4nF and 39.6nF. With the bottom margin being set at 30nF, this means that the interval takes approximately 72% of all values. Is this the correct procedure to solve this...

This is the given schematic. The result should be $$A_u = \frac{R_b g_{21}}{1 + R_b g_{22}} = -50$$ and the way I wanted to tackle this problem is by stating $$A_u = \frac{-R_b i_2}{u_1} = \frac{-R_b (g_{21} u_1 + g_{22} u_2)}{u_1} = \frac{-R_b (g_{21} u_1 + g_{22} u_2)}{g_{11} u_1 + g_{12} u_2}...

Homework Statement Question is simple: what happens when ##DNL = -1 LSB## where DNL signifies differential nonlinearity and LSB stands for Least Significant Bit. It is also required to try and sketch such condition. Homework Equations Equation for differential nonlinearity: $$DNL(i) =...

Well, that's embarrassing, I should have read a bit more theory on BJTs. Obviously that was my flaw here. Thank you so much for helping me out and pointing me in the right direction. Solved!

Hi, before you proceed with reading this question, I would like you to know what I do not expect anyone to solve this task for me. I have a problem with a single step in the solution and I'm only asking you to help me with this one step. 1. Homework Statement Compute ##R_B## so that Q-point of...

That helped a lot, thank you for your time and patience!

Yeah, I was wondering why this question would even exist or how does it pertain to the parameter-dependent integrals. I was contemplating this task for awhile and I don't think I'm even going in the right direction. I'm sorry for posting nonsense, but this is the line of reasoning I took trying...

Hello everyone! I'm a student of electrical engineering, preparing for the theoretical exam in math which will cover stuff like differential geometry, multiple integrals, vector analysis, complex analysis and so on. So the other day I was browsing through the required knowledge sheet our...

I apologize for the late response, did read through the post and managed to finally solve the task. I would like to thank everyone here for helping me out on that one, I appreciate your time and effort! Really helped me a lot! Hope you're all having a fantastic Friday ;)

1. The problem statement, all variables, and given/known data Given is a second order partial differential equation $$u_{xx} + 2u_{xy} + u_{yy}=0$$ which should be solved with change of variables, namely ##t = x## and ##z = x-y##. Homework Equations Chain rule $$\frac{dz}{dx} = \frac{dz}{dy}...

Thank you so much! I actually managed to find a solution this way, thanks!

1. The problem statement, all variables, and given/known data Task requires you to solve a partial differential equation $$u_{xy}=2yu_x$$ for ##u(x,y)##. A hint is given that a partial differential equation can be solved in terms of ordinary differential equations. According to the solution...

This was actually incredibly helpful! Thank you for your time and patience! I finally understand how it works, thank you!

Hello everyone! I'm working on a simple app for a project at the university and I'm having problems accessing the SQLite data in RecyclerView. I suspect that the problem lays in a connection with an activity that includes the RecyclerView and the RecyclerView adapter itself. My project, in the...
