Python plotting missing

hello, I have simulated Bandpass filter using an op-amp. I am getting well and a good plot in Ngspice plot. But In python plot, I am not getting db plot(plot_db). How can I get db plot in python plot?

Hello,

We need to place plot_db at the output. As db is 20logv(in), even though it can be plotted using Ngspice, the py plot shows w.r.t frequency or time.
If we take 20log(10) and 20log(100), it will be 20 and 40, whereas python plot will be using ms for time/voltage and the frequency plot will be plotted using F=1/T.

of course, i placed plot_db at the output and also moreover i got frequency plotting in Ngspice plot...
but i didn't get frequency plot in python plot.
how can i get frequency plot in python plotting?

Hello,


Refer Low pass filter/High pass filter from "Examples" folder in eSim-1.1.2
