Convolving a signal with its impulse response in MATLAB

  1. Sep 23, 2012 #1
    1. The problem statement, all variables and given/known data

    We're supposed to convolve the signal

    x[k] = u[k] - u[k-8]

    with its impulse response

    h[k] = sin(pi*k/4)*( u[k] - u[k-8] )

    with the help of MATLAB.


    2. Relevant equations

    3. The attempt at a solution
    The thing is that we don't know how to do this in MATLAB. We think it's something really easy, but we just can't figure it out. We've been trying to find information on Internet, but nothing comes up! Also, we're pretty sure that we're supposed to put

    h[k] = sin(pi*k/4) * x[k]

    - it's pretty obvious from the exercise :)

    Can anyone help us? We will appreciate it! :)

    Did you look up the u[k] function, and implications of it?
