Matlab project-echo canceler

  1. Nov 22, 2009 #1
    I have done numbers 1 and part of 2.

    I got the transfer function to be 1+(alpha)*exp^(-sT). For part 2 i was able to get that the transfer function for the echo canceler was 1/(1+(alpha)*exp^-sT). This is where my trouble begins, i do not know how to expand it to an infinite series and then from that getting the impulse response of the echo canceler and then truncating that. I would move on to the Matlab part but i have never done matlab before and do not even know where to begin on that part. My teacher said this program could be written in just a few lines and all we would need for commands were filter, sum,zeroes and plot. Any help would be amazingly appreciated. Thanks yall.
