I am assuming a good idea for making this active filter (which can be used as a bandpass) is to keep R2 as high as possible and R1 as low as possible, so that Q can be high. Would that be right? Then I can accordingly adjust C1 and C2 for the resonant frequency I need.
Are there anything else I can do to make it closer to the ideal bandpass filter?
How is called an "infinite gain" (like the link says under the title "Infinite Gain Multiple Feedback Active Filter"), or does "infinite" just go to say that it can be as high as possible? Is it a good idea to keep my gain as high as possible?
