Providing clarification
Feb 13, 2019 at 21:57 comment added BestQualityVacuum Thanks again for your reply. The thing is though, wouldn't the negative frequency response be shown in the negative spectrum? I ran the same numbers you had for L, R, and C, and my graph definitely did not look like what you had. In my code, I had values of omega range from -1*10^6 to 1*10^6, so I don't think it's a problem there.
Feb 13, 2019 at 18:44 comment added sstobbe Yes you can proceed that way, though I'm sure what your are expecting the negative frequency response to be. The bode plot above is for omega>=0, and R is lowered by a factory of 10 to show peaking in the filter.
Feb 13, 2019 at 18:29 comment added BestQualityVacuum Thanks for your reply. I see how using the 'tf' function makes things easier, but mathematically, shouldn't my values for impedance (ZL, ZC, ZR) also work? Writing them out like that worked when demoing an RL and RC first order high/low pass filter, but what makes it impractical here?
