WebMay 27, 2011 · The Fourier series for f_1 is what you are calling the half range cosine series. Of course, you could also extend f to make it an odd function. That is, you could define f_2(x) = f(x) for 0 < x < pi/2, and f_2(-x) = -f(x) for -pi/2 < x < 0. The Fourier series for f_2 contains only sine terms and is what you are calling the half range sine series. WebAug 27, 2024 · we see from Equation 11.2.6 that the Fourier series of f on [ − L, L] is. an = 1 L∫L − Lf(x)cosnπx L dx, and bn = 1 L∫L − Lf(x)sinnπx L dx, n ≥ 1. Note that a0 is the average value of f on [ − L, L], while an and bn (for n ≥ 1) are twice the average values of. on [ − L, L], respectively. hi-q antenna manual
