My question asks me to sketch the following:
[tex]g(x) = \delta (y+a) + \delta (y) + \delta (y-a)[/tex]
The Attempt at a Solution
I think this is it, but am I correct? I don't recall actually seeing a delta function other than a Kronicker(sp?) delta function, and I'm pretty sure that this isn't one of that type. Research on the web therefore leads me to this (because after trawling my notes I can't actually find anything about it in the entire course!).
