I'm sure there is a really simple explanation for this but I can't seem to figure it out. I am sweeping the series resistance of the source voltage and I am trying to see the transfer function output. When plotting the V(out) and V(in) plots separately, the different plots are shown for increasing values of series resistance. However, when I "add trace" as V(out)/V(in), only one plot appears. How do I get plots of V(out)/V(in) for all the different values of series resistance?
Alternatively, is there a way I can plot V(out)/V(in) directly rather than going into the waveform viewer and using "add trace"?
Any insight on this problem would be greatly appreciated.
