Part II: MATLAB Microproject

Continue to test the spfirst$\_$v$173$ toolbox.

You can test it by finding the GUI inside the folder fseriesdemo, which is started by running the script fseriesdemo.m$.$

a$)$ Experiment with the GUI to create square, triangle, and sawtooth periodic signals. Investigate which of these signals have the property that roughly $50\%$ of all the amplitudes have value zero. Produce screenshots to justify your observations$/$choices$.$

b$)$ Next, reproduce, as close as possible, one of the figures below from Appendix C$.$ Please choose between either C$-7$ or C$-9.$ Your documentation for part II is a multi$-$page PDF file with plots$/$screenshot $\frac{?}{?}$ snips. You should be able to create a single file with all figures in one file named starting with your Last Name. Also add your last name to the plots wherever possible. The file may be uploaded to Blackboard.

Figure C$-7$ Summing harmonic components for a $50Hz$ triangular wave via finite Fourier synthesis $($C$\mathrm{.}10).($a$)N=3.($b$)$ Up to and including the $9^{th}$ harmonic $($i$.$e$.,N=9).$ The constant DC level of $\frac{1}{2}$ is indicated.

Figure C$-9$ Summing harmonic components for the half$-$wave rectified sine signal using finite Fourier synthesis $($C$\mathrm{.}10).($a$)N=2.($b$)N=8.$
