Magnitude Magnitude Magnitude 1.0 0.5 0.0- -0.5 -1.0 1.0 0.5 0.0 -0.5 8. Write a python program that plot the fundamental hormonic and the 2nd, 3rd, 4th, 5th, 6th, 7th, 8th and 9th harmonic of the problem 7. Hint: Start with the program from #7 and modify it by adding a loop to produce the harmonics. Your final graph should be look like the figure below.
