Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I was assigned a lab that requires me to build the attached circuit and show how the output signal is the integral of the input signal. Basically I cant understand what the function of the 10MOhm feedback resistor is. Its giving me a headache when I try to derive my proof for the integrator, and part of the lab is to explain its significance and what would happen if it were removed.

I dont know if I should be posting this in homework help but this isnt really a math question so I figured I could try here 1st.

Thanks
