    Hi all,
    I was studying convolution sum(discrete time)..from Signals and systems(haykin)and Digital signal processing(Proakis)..And I found that I was able to understand the graphical approach to of calculation but not the mathematical one..It's too hazy in both book..(I just can't get hold of a single thing).

    Can any body help with some sites/reference books to understand the mathematical approach please

    Here's a link to an article on Wikipedia--http://en.wikipedia.org/wiki/Convolution. That should get you started. At the bottom of the page are a bunch of links and references.

    If you can get a copy, have a look at Signals and Systems by Oppenheim and Willsky.

    Did you read Chapter 6 of Smith? It's all there, and it is FREE for the downloading.

    Below is a link to my video blog at my website on the topic you are discussing entitled Convolution Sum for Discrete-Time Systems

    http://freedomuniversity.tv/blog/?p=20

    You can also find other related videos I produced at http://YouTube.com (type drjctu in the search box). For example, I've also produced videos on the convolution integral at YouTube.For your particular, question, here is Part 1: http://www.youtube.com/watch?v=iG-Lp7D5uhE.

    Hope this helps!

    Let me know if you have any questions at john@e-liteworks.com.
