Homework Statement
I have to plot some data for a lab writeup. It's based on the frequency response of fluid catheter-transducer systems. Part of this writeup includes making Bode plots for the gain and phase shift. I know how to plot my data; the problem that I am having is that I want to try to fit a trendline that closely follows the data, but I don't know how to do this.
1) What is the function (as in x/y) for a theoretical Bode plot for a second-order system?
2) Is this the right way to go about this or is there a better way?
Any insight would be much appreciated.
