2. Suppose the Laplace transform of a causal signal x(t) is given by
s² +2
X(s) =
S³ + 1
Using the lookup tables for standard Laplace transforms and the Laplace transform
properties, find the Laplace transforms of the following signals. You do not need to
simplify the expressions.
a) x₁(t) = e² x(t) + 38(t − 1) − (t − 2)² u(t − 2)
b) x2(t) = x(2t - 1) + et u(t − 2)

- This is the 3rd time i'm asking this. SOLVE THIS AND FIND V0 , the last answer i was given is -2V which is not even one of the listed options. the listed options are: 12V,4V,24V,6V. first answer given to me was 4V but after i simulated on ltspice albeit i'm not sure if i simulated correct i got a different answer and when i solved it myself i got a different answer. this is my last remaining question. PLEASE SOLVE CORRECTLY AND PROPERLY. NODAL ANALYSIS IS BEST TO USE HERE. IT IS AN IDEAL OP-AMP. SIMULATE USING LTSPICE AND GIVE ME FINAL ANSWER IF POSSIBLE AS THAT IS ALL I CARE ABOUT NOT THE PROCESS. THANK YOU.
