Combinational Logic Exercises


  1. Construct the truth table for the following combination of gates:

    What is the connection between this circuit and the one considered in group exercise?

  2. Prove that the following two circuits are equivalent by constructing the truth table for each one:

    Note that the three binary inputs generate 8 unique input states; hence, each truth table should have 8 rows.
