## Homework Statement

f(t) = 1 0<=t<T/2

-1 T/2 <=t<=T

ie. step function.

frequency w_0 = 2pi/T

## Homework Equations

## The Attempt at a Solution

What's the definition for the fourier coefficients a_n and b_n again? Not the one in wikipedia.

a_n = \frac{1}{\pi} \int_0^{T/2} 1*cos(nt) dt +\frac{1}{\pi} \int_{T/2}^{T} (-1)*cos(nt) dt

[/tex]

[tex]

b_n = \frac{1}{\pi} \int_0^{T/2} 1*sin(nt) dt +\frac{1}{\pi} \int_{T/2}^{T} (-1)*sin(nt) dt

[/tex]

I think the normalization factor is incorrect, which is why i asked for the definition, I think it was 2/L where L is the length of the interval - i can't remember.

If you can't remember, do you have a book?

No, that's why I asked.
