MATH SYMBOL Help Figure?

  1. Nov 8, 2009 #1
    Hello there! Im in a class of signal and communication systems and found this symbol:
    ‹[·]› But I cant figure what it means, teacher told us to research it. Been reading books like crazy and cant find anything. Hope you can help me.

    I put a picture of how he used it, if that helps you.

    looks kind of like a fourier transform of [.]

    Well, the problem isnt the whole operation, because it is kinda fourier transform. Thing is what does [.] mean?!

    Sometimes authors will use a dot to denote where the thing to be operated is supposed to go. For example, the inner product is linear in the first term can be written as:
    < . ,u> is linear for any fixed u. Maybe something similar to that? Not sure about the brackets

    the average value of a function f is usually written as [tex]\frac{1}{b-a} \int_{a}^{b}{f(x)dx}[/tex]

    so set a = -T/2 & b = T/2 & then T--> infinity...... that's more like it
