Define signal x(t) = u(t−1)−u(t−2.5)−2δ(t− 4)+δ(t −6). (a) sketch y(t) = $ t −[infinity] x(τ )dτ . (b) describe a simple change that can be made to the right-most delta function in x(t) so that y(t) = $ t −[infinity] x(τ )dτ has finite energy. (c) sketch z(t) = $ [infinity] t x(τ )dτ . (d) determine real constants a and b so that w(t) = x ? t−a b ? has a region of support
