Unformatted text preview: zero . 6.7. Bubble match the schematic of Figure 6.14 to have a noninverted output. Then, write the logic function the circuit implements by inspection. The bubble matched circuit with noninverted output is: The logic function for this circuit is: F = (A’+B’)E + (C’ + D’) = (A’+B’)E + C’ + D’ A B E C D F Last updated: 10/1/2006 6.8. Bubble match the schematic of Figure 6.14 to have an inverted output. Then, write the logic function the circuit implements by inspection. F = [(AB + E’)(CD)]’ = [(AB + E’)CD]’ 6.9. Use DeMorgan’s to verify that your answers to the previous two problems are equivalent. F = [(AB + E’)CD]’ = (AB+E)’ + (CD)’ = (AB)’E’ + (C’ + D’) = (A’ + B’)E’ + C’ + D’ The final line is the expression we obtained in problem 6.7. Thus the two answers are equivalent. A B E C D F...
