Fourier series question

  1. Oct 8, 2006 #1
    A rectangular pulse train with peak-to-peak amplitude A = 2V (peak amplitudes are +/- 1V), period T0 = 1ms, pulse width a = 0.5ms, dc offset zero volt.

    How do you find the dBV of the one-sided Fourier coefficients cn for 0 ≤ n ≤ 12?

    n refers to the harmonic #? Is the fourier coefficient just the amplitude of the harmonic?

    You need the rise and fall times as well. Are those given in the problem statement?

    I guess if they are assuming zero rise and fall times, you get the classic odd harmonic fall-off, right? What is the equation for that?
