noisy bode plot data

Hi,

i have some pretty noisy bode plot data that i would like to do a curve fitting on. Does anyone know if matlab has some built in frequency response curve fitting functions?

Thank you

There isnt anything designed for smoothing frequency response curves specifically. Try using the SMOOTH function or other smoothing functions in the Curve Fitting Toolbox.

If you dont have the Curve Fitting Toolbox, you could design your own moving average filter.

For more fine tuning of the data, you can try using some of these Frequency Response Data Models.
