i was doing some homework and one thing I had to do was to derivate the transfer function of a given bandPass. I have done it myself but i dont know if it is correct nor if i followed the right path / right assumptions. I'd be happy if someone of you could look at it and give me some feedback. Important: In my notes Ua = V(out) and Ue = V(in) the rest should be (I Hope) self explanatory.This is how I've done it:
And this is the bandpass:
Thank you in advance!

Yes, it appears to be correct and you have followed the right path. Apart from the number "1" missing on the first line - you put \$j\omega C\$ rather than \$j\omega C_1\$. You also omitted brackets around the top line numerator but corrected that in the denominator.
I derived it my way (to avoid me being influenced) and got the same answer.
Feel Happy!
Here's my scrappy mess: -
This is why you should take the time and use Latex!! The very bottom line is me just checking the j terms match yours.
