hi guys
what is this circuit an how we can proof the formula with KCL or KVL ?

 

hi guys

You'll need a little more than that. Is this homework?

 

It's an inverting amplifier that nobody would ever use in the real world, so it must be homework. Mods notified.

yeah just homework...

 

homework

For homework, you need to show your best effort. No one will give you an answer; at least they're not supposed to...

ook . thank u

 

I'm assuming that the Y values are admittances (or conductances) and not resistances? Is that correct?

Here's a huge hint. Focus on the voltage at the crossing point of the left four resistors.

 

Step 1.
Label the nodes.

If you don't know what a node is, you have no business doing this homework.

Or a multiple feedback bandpass filter. But no one would ever use one of those.

 

Hello,

@joeyd999 , The MFB is not only for bandpass.
There are also low and highpass versions.
It all depends on wich element is a capacitor or resistor.





@Mil Nik , you should see the Yx elements as impedances in your task.
As you can see they can be also frequency dependend, as in the filters.

Of course. I was giving 1 example where the circuit was useful.
