Hi,
I'm learning butterworth filter designing, and I have gone though the Electronics Tutorial (https://www.electronics-tutorials.ws/filter/filter_8.html). I have a question, please can you clarify my question.
Where this value '10' is comes from (marked in Red in the above text)?. Is this gain of Amin?.
From the above text, I have illustrated the graph of the gain of max and min.
If the above graph is right, then I want to design a circuit Amax=0dB, Amin=-120dB. Therfore, what will be the gain of Amin?.
Please can you answer above two question (marked in Red)?.
