Friday we have started with the procession of the signals.
We worked out a function for reading, plotting and transforming the signal to the frequency domain. We thought this would be the best way to quickly
extract the essentials we need from our signals. We also found an algoritm for finding the 'touchpeak' from the signal, the one we need.
This is usefull, because we now can start comparing multiple samples from each key. (we already have 20 samples of the key "a")
We could not yet find a way to directly save the important plots (the one from the frequency domain) to a file, so we could open them all together and compare them. This we will search for next tuesday.
We still are wondering how to compare the frequency-plots, wether we have the right part of the signal, and if these frequencies are correct...
