Fourier Series of Even Square Wave

  1. 1. The problem statement, all variables and given/known data
    [itex]-0.5\leq{t}\leq{1.5}, T=2[/itex]
    The wave is the attached picture.

    I need to determine the Fourier Series of the wave in the picture.

    I know that [tex]f(t)=a_0+{\sum}_{n=1}^{\infty}a_ncos(n\omega_0t)+{\sum}_{n=1}^{\infty}b_nsin(n\omega_0t)[/tex]

    where [itex]a_0=\bar{f}=0[/itex] due to being an even function. Furthermore, [itex]b_n=0[/itex] due to being an even function also.

    That leaves,


    Is this suffice as an answer, or am I missing something? My textbook is lacking examples so I just would like to know if I am doing it right. Thanks!
