Unformatted text preview: As it turns out, Expresso expects that all possible input sequences be listed out in the input file, even if the corresponding outputs are Dont Cares. The other option is to use a reduced size input file, but then the output is not well minimized, and the implementation complexity in LogicWorks is much greater. Therefore there is a tradeoff here. IN general, it is more beneficial to have a fully minimized expression before building the circuit. running expresso on the input gives the following output Q0* = Q0'.Q1.Q2'.N + Q1.Q2.D + Q0.Q Q1* = Q0'.Q1.Q2'.N + Q2.Q'.C' + Q1'.Q2'.D + Q1.Q Q2* = Q0.Q'.N'.C' + Q1'.Q2'.D + Q1'.N +Q2.Q DG = D'.N'.C' + Q1.Q2'.D + Q0.C' Rc = C...
