1. The problem statement, all variables and given/known data Let y(t) be the convolution of x(t) with h(t), show that the area under y(t) is the product of the areas under x(t) and h(t) 2. Relevant equations Convolution definition 3. The attempt at a solution I found a derivation but it skips a step, uploaded it here: htt p://i50.tiny pic.com/s15dus.jpg
