Hi Netra N., I noticed your profile and would like to offer you my project. We can discuss any details over chat.
The project can be structured in 2 phases and shall be written in Octave (~Matlab) code. 1. Phase: File Merging of 1 ASCII and 2 binary files via time stamps (sample files available) 2. Phase: Complex FFT (or DFT?) of down-converted high-frequency IQ data; extraction of complex signal values for a selctable number of known frequencies per time stamp. Signal values to be extracted for all time stamps in an automatic routine. Results to be written in an ASCII file with given structure. Data visualisation. 3. Phase: Follow-on project: Post-processing on GPS-based 3D-position & 3D-orientation data and merging with ASCII File from phase 2. See also flow chart attached with details of phase 1. Details of phase 2 still in progress.
I need to interface a DAQ / IEPE ADS127L01 with STM32H753. The DAQ has a SPI output at 24 bits & 500Ks/secs. No processing is required within STM32. Only, Data from SPI-Peripheral to Buffer to Peripheral (OUT) is required / DMA. The out DATA needs to be in ETHERNET Protocol. Finally, this data on Ethernet Protocol should be tied to MATLAB for FFT.

For this work I need to use the programs in Java, processing or Octave/Matlab to prepare a narrative on digital waveforms, spectral analysis using the FFT and the Spectrogram to demonstrate your knowledge of how they work. Make sure that each plot can clearly illustrate the shape of the waveform, i.e. if you have to zoom in to get this, do so. A thick coloured block is not acceptable. The results from your plotting should be placed into a powerpoint presentation and along with the plot a sound file should be inserted into the page (it should be imported as mp3 to save space). The documents should also show on the following slide to each plot the programming scripts to generate the wave and its graph. The graphs should have titles, labelled axes and have a caption in the document Mo...
