Foorier series from haar function

  1. May 16, 2010 #1
    [tex]f(x)= {1, 0<=x<3/4}[/tex]
    [tex]f(x)= {-1, 3/4<=x<=1}[/tex]
    calculate the foorier function with haar group
    here is the solution:
    [tex]L_1=\phi_{0,0}(x)=\begin{Bmatrix}1,0\leq x\leq 0.5
    -1,-0.5\leq x\leq 1
    i dont know why i have latex error here the code is
    L_1=\phi_{0,0}(x)=\begin{Bmatrix}1,0\leq x\leq 0.5
    -1,-0.5\leq x\leq 1

    That's Fourier...
    Is there a typo above? Otherwise, why not say that f(x) = 1, 0 <= x <= 1?

    Also, I fixed your LaTeX below.
    What is the above supposed to be?

    i have changed the function
    there was a mistake
