Signal square waveform

  1. Apr 6, 2013 #1
    1. The problem statement, all variables and given/known data

    Alpha=0.91 ,beta=2.92, T0=0.91

    2. Relevant equations

    The value of a0 for the square waveform

    3. The attempt at a solution

    1/T0 * area = 1/0.91*(2.92-0.91)*0.91

    T0 has nothing to do with it.
    (I assume a0 is the first coefficient of the cosine Fourier series.)

    Hi Sueyeeyab! http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif [Broken]

    Expressions with brackets must be written unambiguously, viz.,

    (1/T0) * area = (1/0.91)*(2.92-0.91)*0.91

    To determine the average area, you must first sum the individual areas (or use a method which is equivalent). There are two rectangular areas to sum.
