1. The problem statement, all variables and given/known data Evaluate (simplify) the following expression: y(t) = ∫0∞ e2(t + 2τ)δ(t + τ)dτ = 2. Relevant equations Shortcut signal expression techniques, integration of an exponential signal and impulse signal, other techniques that are probably unknown to me 3. The attempt at a solution (t + τ) = a; τ = -t + a; dτ = 0; =1 but this can't be right at all. I know you're supposed to integrate something but don't really know what (or how it works in this case). Any hints would be greatly appreciated, thank you!
