I'm designing a circuit that simulates the impedance behavior of a real world speaker, which is not purely resistive and looks something like this:
I already got the basic circuit but need to tweak the resonant peaks and valleys and what not, so I need to plot an impedance vs frequency graph but I haven't been able to find how, I put a voltage probe as seen in the image below and the db vs freq. graph seems about right although inverted so I guess the probe should go there, however when I tried to put a current probe in different places I got different errors running the graph, where should I put it?
For the impedance part I searched online and found hints to the Add Trace command, but I've never used it before nor could I find tutorials or info about it, how does it work? I assume I should input the voltage probe as P1 and the current probe as P2 and then for the expression P1/P2 to get ohms??
Thanks in advance for your help :)
Here's my basic circuit:
