Home work 5 Problem 1: rezolvati problema corectiei pixelilor folosind toyMachine cu regula mai precisa: s’(t) = if (s(t)= 0) then (3×s(t-1)+5×s(t-1)+5×s(t+1)+3×s(t+1))/16 else s(t) Problem 2: desenati cu porti logice cu doua intrari si inversoare structura unui decodificator cu 4 intrari pornind de la definitia recursiva a DCD-ului (vezi slide 23). Problem 3: proiectati un circuit care calculeaza 2 m unde m=2 n. Comparati size-ul circuitului rezultat cu cel al circuitului care calculeaza valoarea lui 2 n. 2014Digital Integrated Circuits - week five24
