    Hello all,

    First off I apologize if this is a simple question but I am not that great at circuit analysis and it has me stumped and I haven't been able to find a solution yet.

    I have a butterworth high pass filter and I need to calculate the input impedance of it. I was wondering if there is a system or general method for analyzing these types of circuits. I have found resources to analyzing other op amp circuits but I have been having trouble extrapolating them to this problem.

    Any guidance or help would be greatly appreciated.

    Thank you,
    Eric

    Thank you very much! That is extremely helpful. I thought I did a good job searching for something like that, apparently not though. Sorry for the repeat question.

    Thank you again,
    Eric
