Third-order Butterworth Filter Design and Transfer Function

[@umutaydn6184]

we found the transfer function 4 times larger than the first transfer function. Why is that?

Glad that this op amp circuit of the Third-order Butterworth Filter Transfer Function is useful. I suggest you review your calculation of the first transfer function to make sure your derivation is correct.
