Fourier Series

  1. Jan 19, 2005 #1
    Okay. so i have a problem that i'm finding tricky to work backwards from.
    I'm given the coefficients

    Period 4 and x(t) is continuous.
    a_{k} = 0 if k=0
    a_{k} = j^k*sin(k*Pi/4)/(k*Pi) if k!=0

    Supposed to find x(t).

    Now i've tried a few things but have come up with many different answers. Mostly I am confused as they all depend on the value of k. I am obviously lost as to how to reverse this.

    Meh. Nm. i read ahead and used the fourier transform pairs table. Also noting that j^k gives exp(j*k*Pi/2) which is just a phase shift to the square wave.
