I have got the biomedical (EMG,ECG) signals in .wav format. Can i process biomedical signals in matlab. And how i can read it? Will the result be accurate?
No products are associated with this question.
You can definitely read and process biomedical signals in MATLAB. MATLAB has several routines for reading ‘wav’ files: http://www.mathworks.com/help/techdoc/ref/wavfinfo.html .
As for processing them, that depends on what you want to do. I suggest that you search the File Exchange and the Web for MATLAB toolboxes and routines others have developed to analyse EKG and EEG data. Here's one for EEG: http://www.brain-smart.org/.
