For my college assignment, we have been given several tasks. However, this one question is asking to make a software filter for the longitudinal/lateral acceleration for a certain data set of a rally car. They have also asked us to compare the filtered and unfiltered signals.

As someone just starting out in MATLAB, I have absolutely no idea how to do this. If anybody knows how to do so, please help me out. Thanks in advance!

Hi, my sincere apologies for violating community guideline. However, I did go through MATLAB documentation as much as I could and I was unable to find anything related to creating a filter for Longitudinal acceleration. Is there anything else I can do, please let me know.

Thank you!

Well, you have a decision to make.

Do you want to treat the coordinates as being small enough range to be able to treat them as cartesian on a flat plane? Or are the distances or positions involved large enough that you need to work in spherical or geoid coordinates?

I would point out that there are very few rally cars in the world operating at latitudes high (or low) enough that at rally-car speeds that the geoid correction becomes important for any practical purposes. For example with typical GPS you can only measure position down to 1 to 3 metres; if you add a fixed-position extra-transmitter you can get down to about the cm position range, so it probably does not make sense to worry about milli-G calculation precision.
