Hello,
I did an experiment where an app on my phone recorded the frequency of my car's horn. I did it in two situations (Note: I opened the bumper of the car and recorded right above it):
1. Horn while engine and air conditioner are turned off
2. Horn while engine and air conditioner are turned on.
I've attached pictures with the data that I recorded with a graph for both experiments. So my goal here is to try and find the Fourier Transform of both of those graphs. Here is where the difficult part (for me) is. I'm not perfect with this topic and suck at coding. I know that the formula requires you to have a function of time, but since this is a non-periodic signal, I have no clue how to do it. I'm sure that there are simulations out there that can do it for me, but I find it more interesting to do it manually. However if there is no way to do it manually, please recommend a simulation.
Also, I'm in my final year of the IB Programme (I'm 15), so please try to make your explanations sound as simple as possible. If you don't want to, then its fine by me: more opportunities to learn new things.
