Digital Logic Circuits Equivalence

Are the two circuits equivalent? explain your answer…

Show My Homework - Digital Logic


For the first circuit

(A or B) or C = A or B or C

because all or operators have the same precedence

For the second circuit

not (A and B and C) = (not A) or (not B) or (not C) (see de Morgan laws)


The two circuits are not equivalent. This can also bee seen by writing the truth table for each circuit.
