1.The Laplace Transform of f(t) is F(s) (i.e., L[f(t)] = F(s)). Assume thatWhen s= 3,Please find A+B+C+D=?《Hint:L[th(t)]・L[g(t))]=L[f(t)g(t)]》

2. Given one logical circuit (as shown in Figure 1) and the corresponding truth table is providedin Table 1 as well. We assume the initial state of clk signal is 1. In addition, one value will beassigned to input D every one clock cycle. The output of this circuit is Q and Q' and the inputsequence of D input is
