how can i derive the formula of cutoff frequency of a second order low pass filter?
it is a simple two stage RC filter, but when it comes to derivation of cutoff frequency the equation i face with extraordinariliy complex (at least for me)
can anyone give a suggestion?
(may be a link to such a derivation?)
thanks in advance
