Homework Help: Help with convolution

  1. Oct 4, 2014 #1
    convolve the following

    h[n] = δ[n-a] + δ[n-b]
    x[n] = δ[n-c] + δ[n-d]

    i understand that the convolution is y[n] = h[n]*x[n] and i know how to do it with number instead of letters however not quite sure how it would work with the letters, its not possible to view when a & b will overlap c & d.

    Any help would be appreciated

    What is your definition of ##\delta[k]##? When you say you understand ##y[n] = h[n]*x[n]##, what,exactly, do you understand? In other words, what would be the actual formula for ##y[n]##?
