Right-click on “V(vout)” in the plot window and change the text in the dialog box to “V(vout)/Vi”. This plots the large-signal gain of the circuit shown on the right. Although we can compute and plot it, the large-signal
WebAbove I used LTspice as an example to create such data points. But such Bode plot data could be from a network analyzer or a data-acquisition system. Having only the Bode plot data points of a system/circuit but not the circuit diagram, how can we obtain the transfer function? transfer-function bode-plot Share Follow edited Jan 28, 2024 at 14:27 WebJun 28, 2024 · 6/28/21 #130638. Ryan, If you have Bode plots, then you have complex impedance vs. frequency. In LTspice, you can use FREQ tables to enter frequency tables into a simulation. They use the Laplace function if you use them in a .tran simulation. Please be aware that Laplace can have serious problems in .tran.
