I am not even sure how to start with this lab and how to use the function in Matlab. If someone can explain how to use the fourier transform fuction I would greatly appreciate it.
Questions:
Use Fourier transform in Matlab to numerically analyze the following functions
  • Create a dataset for the function below for t from 0 to 20 seconds and N is your group number. Plot the function in the time domain.
  • Use the function FFT (f, tN), tN is the length of time (t) in Matlab to compute the discrete Fourier transform of the function above.
  • Plot the magnitude and argument of the Fourier transformed function in frequency domain.
