2 Find the trigonometric Fourier Series for the periodic signal shown. That is, find a, a,, and b. Use these Fourier coefficients to write the expression for the Fourie series function, f(t). 8 f(t), volts 0.2 1 0.4 t(sec.) For Problem 2: I- Using your Fourier series result of Problem No.2, a) plot the fundamental and the first three harmonics in one figure. b) plot the sum of the harmonics including the average value (DC content) as n goes from 1 to 9. (where n represents the summation index in the Fourier series expansion.) c) Comment and explain the results of a and b above. Ensure to demonstrate understanding. II- Using the symbolic toolbox, derive expressions for a, a, and b, and compare results to those of Problem No.2 2 Find the trigonometric Fourier Series for the periodic signal shown.
