Fourier Series

  1. Jul 3, 2010 #1
    1. The problem statement, all variables and given/known data

    Given the first cycle of a waveform:

    f(t)=2u(t)-2u(t-1)+u(t-2)-u(t-3)

    -- Plot the first cycle of the wave form
    -- Find the Fourier Coefficients

    2. Relevant equations

    Given above

    3. The attempt at a solution

    No idea yet. Will appreciate any help.

    Although the author should have specified the period, one might assume from what you were given that the period is P = ?

    If you draw another cycle for negative t, would the function look even, odd, or neither?

    What are the formulas for an and bn, remembering that u function has values of only 0 or 1.

    Answering those questions might get you started.
