Homework Help: Convolution Property

  1. Sep 19, 2007 #1
    I know this is elementary but I'm having trouble with proofs of some of the convolution properties:

    1. f * (g * h) = (f * g) * h
    2. (cf) * g = c(f * g) = f * (cg)

    Please show me the proofs step by step or lead me to a link where the detailed proofs are displayed.

    Sorry for such elementary questions. I don't know why I'm not seeing it.

    What does each letter represent? How is a * b different from ab?

    By * I mean convolution.

    I would think most people take


    as product while

    a * b

    to be convolution.

    f and g are obviously functions and c a constant.
