How to graph magnitude plots for basic 4-pole filters? I have developed magnitude plots for basic one-pole and two-pole filters derived from various Physics PDF's and tutorials I have found online and calculated from:

But I cannot figure out what the correct plots for any simple four-pole resonant LPF, HPF, BP, &amp; BR filters would be in the same terms. 

Any help on what equivalent simple four equations would be? Thanks.

Play the variable n.
