What's the advantage of building an active filter having more than one stage vs only a single stage?
If you use multi-stage, would you not introduce pole pairs with higher Q factor, and thus producing overshoot and oscillation in your time response, plus you also have to buy more OpAmps, resistors and such?
(two 100V/V Sallen and Key low pass filters)
