Can heart sounds and ecg be simultaneously recorded and downloaded onto matlab

Can heart sounds and electrocardiogram be simultaneously recorded and downloaded onto matlab.

how does one analize the two using fast fourier analysis

Answer 1

[Wayne King]

The answer is yes, depending on whether you can interface the hardware with MATLAB. In a former life, I used to record ECG and EEG into MATLAB using the Data Acquisition Toolbox and an NI board.

In terms of "fast" Fourier analysis, I think every computer language implements "fast" Fourier analysis as opposed to computing the DFT by brute force.

Base MATLAB ships with fft algorithms; the Signal Processing Toolbox extends the capabilities of base MATLAB for Fourier analysis.

Answer 2

[Priya]

Have a sound recording saved as a .wav file I did import it on to MATLAb shows up as a bunch of numbers.

How do i go about doing a fourier analysis on it. Did do the entire student tutorial but cannot figure it out. Am an 11th grade student with no experience of MATLAB.

Thanks
