    We are more than willing to aid in your understanding, but we must insist that you do the work. Can you make an attempt on these questions, and say why you think it is correct?

    I think what beenthere is saying is that you need to show us the work you have done.

    In the second problem, the first opamp circuit is a Sallen-Key highpass filter and the second opamp circuit is a Sallen-Key lowpass filter. Depending on the relative values of the corner frequencies of the highpass and the lowpass, the overall frequency response could be a bandpass or a bandstop (notch) filter
