Re: Signal analysis with Laplace project http://www.8051projects.net/forum-t3617.html 2009-01-07T22:14:19-08:00 Ajay hmm.. laplace transform... what kind of analysis you want to do with the signal? Re: Signal analysis with Laplace project http://www.8051projects.net/forum-t3617.html 2009-01-07T22:14:19-08:00 Ajay I never seen anyone using laplace transform for this purpose.. why don't you try Fast Fourier Transform? Re: Signal analysis with Laplace project http://www.8051projects.net/forum-t3617.html 2009-01-07T22:14:19-08:00 pajanet 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 Re: Signal analysis with Laplace project http://www.8051projects.net/forum-t3617.html 2009-01-07T22:14:19-08:00 pajanet 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 Re: Signal analysis with Laplace project http://www.8051projects.net/forum-t3617.html 2009-01-07T22:14:19-08:00 Ajay http://www.8051projects.net/downloads37.htmlhere is an FFT program for 8051and here is FFT program for PIC microcontrollerhttp://www.piclist.com/techref/microchip/fft/picspect.htmyou can do spectrum analysis as you want. Re: Signal analysis with Laplace project http://www.8051projects.net/forum-t3617.html 2009-01-07T22:14:19-08:00 pajanet Thanks for the reply, I'll look into it.
