Signal analysis with Laplace project

Hi, I'm starting a project where I need to collect a signal from a pressure transducer and analyze it using the laplace transform where can I find useful info for it?

hmm.. laplace transform... what kind of analysis you want to do with the signal?

I'm trying to make a frequency response analysis, with calculations of damping ratio and natural frequency and then showing this results on a LCD

I never seen anyone using laplace transform for this purpose.. why don't you try Fast Fourier Transform?

Exactly what I want is this:
I have a pressure transducer with a catheter (wheatstone bridge), attached to a bottle, and at the top of the bottle I have a balloon.
If you pinch the balloon the sudden drop of pressure will generate a step signal, the catheter tranducer behavior is exactly like a RLC (second order) system. So I want to analyze this signal and then obtain the parameters that I need

here is an FFT program for 8051

and here is FFT program for PIC microcontroller

you can do spectrum analysis as you want.

Thanks for the reply, I'll look into it.
