Q8: (a) Identify the frequency with the largest amplitude, greater than 10Hz, in each dataset by plotting the Fourier transforms of each dataset (these plots do not need to be turned

in with your assignment). Plot these identified (most pronounced) frequencies vs. the input frequencies, using Matlab, in the form of discrete markers (this plot should be turned in with your assignment). (b) On the same plot, also plot two lines a piecewise line showing the predicted alias frequencies, given by Eq. (1) in the Appendix. Draw a vertical dashed line at the frequency where you predict aliasing to start occurring for each the Arduino's sampling frequency.
