much useful information. So, to clarify: the time of measurement should be on the x-axis and the breathing frequency should be on the y-axis. Then, I suppose, lower amplitudes of the signal will show the slower breathing. What should be done with ...
This shows how the Fourier transform works and how to implement the technique in Matlab. %Fourier Transform of Sound File %Load File file = 'C:\MATLAB7\work\abc_A4'; [y,Fs,bits] = wavread(file); Nsamps = length(y); t = (1/Fs)*(1:Nsamps) %Prepare time data for plot %Do ...

The Short time Fourier transform use overlapping fragments of the signal, the computed transformations are concatenated into single columns to represents a spectro gram, you can start with basic non overlapping example;a signal with 1000 points where each 10...

My data is in 2D (x and y direction) and I would like to inverse Fourier transform only in the x-direction. (Please see attached for the data). I thought about using the commands: ifft(Y, n, dim) or ifftn(Y). But it doesn't seem ideal as these take the IFT o...

When analyzing your code, I did notice the error you're encountering when trying to read the CSV file in MATLAB, let's break down the key areas to check and troubleshoot. Make sure that the file `P02_S09_T01.csv` is located in the current working directory of MATLAB. You can c...
Open in MATLAB Online @ANAS HAMZAH, To get the very narrow bandwidth shown inthe second plot in your PDF, you need to inccrease the duration of the sample of the signal. The spacing between frequencies in the discrete Fourier transform is where T is the duration of the sign...
