A1. A few useful properties of the Dirac delta function The Dirac δ(z) functions is defined by δ(z) = 0 if |メ0, δ(z) = oo ifx-0 but the integral of the function over any interval containing the zero of the argument is unity, Equivalent, if f(x) is continuous at the origin One should treat the Dirac δ function as a limit of a sequence of functions peaked at x-0 As the limit is approached, the height of the peak increases...

how would you do the convolution of d(t-1) and 2(1-e^-t)u(t) (d stands for the dirac delta function) Please show steps. I know you have to delay the second function by 1 but I do not know if you would have to factor out the negative out of the exponential function first.
