This is all me steps, I hope it can explain what i'm trying to do:
\[
V_x\] is:
\[
\begin{equation}
V_x\left(\dfrac{1}{R_1}+sC_2+\dfrac{1}{R_3}\right)-\dfrac{1}{R_1}* V_{in}-\dfrac{1}{R_3}* V_+-sC_2* V_{out}=0
\end{equation}
\]
\[V_+\] is:
\[
\begin{equation}...
My problem is to reorganize and solve this equation
\[
V_{out}=\dfrac{\dfrac{1}{R_1}* V_{in}}{\left(\dfrac{\left(\dfrac{1}{R_3}+sC_4\right)\left(\dfrac{1}{R_1}+sC_2+\dfrac{1}{R_3}\right)}{\dfrac{1}{R_3}}* k-\dfrac{1}{R_3}* k-sC_2\right)}\]
to the solution
\[...
Yes, k is the gain. The funny expressions is coming because I got error when I copied the LaTeX text to the forum.
It should be like this:
\[\dfrac{V_{out}}{V_{in}}=\dfrac{k}{s^2* R_1* R_2* C_2* C_4+s* \left(R1* C2+R_3* C_4+R_1* C_4-k* R1* C2\right)+1}\]
I just change the \cdot to *
Hi,
I need help to determine the transfer function for a Sallen-Key low pass filter. I need help step by step for the mathematics steps for the transfer function.
The circuit is this:
The steps i already have and end up with, is this.
\[\begin{equation}
V_{out}\cdot...
Hi, first sorry about my english, but I will try to do my best.
Im trying to find V from this circuit, but I can´t find an solution. I know without R5, the solution is 2mA*(9kΩ+4kΩ)*(3kΩ/(3kΩ+7kΩ+9kΩ+4kΩ))=3,39V, but how do i do it, if I have a resistor between R3 and R1.
Circuit 1 without...
I solved it, I found some youtube videos https://www.youtube.com/watch?v=W1hu7TZCNRU and https://www.youtube.com/watch?v=UGjMs-CcdPk. I also found this one https://code.google.com/p/altium-designer-addons/downloads/detail?name=MultiPCBProject_v1.0.zip&can=4&q=, i should had read this at the...
Hi,
I’m using Altium Designer 10, and I want to create a PCB for every sheets. I downloaded MultiPCBProject script from this site https://code.google.com/p/altium-designer-addons/. But I still have to disable every single sheet in the ECO rooms, classes etc. Is there a way, to declare a sheet...
