Hi
Me and my team are developing an electronic stethoscope for our final year project....We want to process and visualise the output in MATLAB like the signals from ECG are commonly done.....We are a little doubtful about certain things like:
1. By connecting to which card of the computer and using which intermediate tool can we bring our signal to MATLAB ?
2. How can we make the thing work in real-time ?

Please be quick in replying....Thanks

Hello,

There are several equipments that you can use to acquire the data. I would recommend the lower cost usb data acquisition from National Intruments (NI-USB6009 http://sine.ni.com/nips/cds/view/p/lang/en/nid/14605).

Regarding the second question, in matlab I guess you will need to use a real time toolkit. If you make a search in google (ecg and labview) you will find out many softwares developed using labview. In my opinion, your project is easier to develop in labview.

I?ve used matlab in my final year project to develop a software to generate the antenna irradiation diagram in 3d. After one year, labview released a newer version which had built-in all the 3d graphs that I need. Despite I?ve used matlab before, I think labview would be the best solution for your project, as you can find many already done examples in the web.

Best Regards.

good luck in your project

Guilherme
