Model analysis using Arduino?

[laluvr]

Can we use arduino for modal analysis such as obtaining the Frequency Response function etc..? Please advice me

A stand alone Arduino Uno can not be used to create a frequency response analyzer.  It is to slow.

However, the following link shows how to create a poor mans bode plotter using an Arduino board, an AD9850 and an oscilloscope.

There is a LINX example for the AD9850. This Bode plotter does not measure phase.

A more supplicated frequency response analyzer can be created using Labview and the approach shown in the fallowing link.
