title: Convolving two signals
body: <blockquote>
    <p>Calculate the convolution of the following signals (your answer will be in the form of an equation):<br>
     <code>h[n] = &delta;[n-1] + &delta;[n+1], x[n] = &delta;[n-a] + &delta;[n+b]</code></p>
  </blockquote>
  
  <p>I'm lost as to what I do with h and x. Do I simply multiply them? h[n]*x[n]? I programmed convolution with several types of blurs and edge detectors, but I don't see how to translate that knowledge to this problem. Please help!</p>
