Task 4 - Logic Circuits and Truth Tables (30 marks) Solve problems related to the two circuits (note the circle is equivalent to a NOT gate) below: Circuit 1 is the top circuit and Circuit 2 is the bottom one. O (a) (6+4 = 10 marks) Write down the equivalent logic expression (simplification is NOT required) (b) (11+7 =18 marks) Write a truth table that shows the final output (O) for inputs A, B and C (Showing all your working out and intermediate steps, i.e., the output of each gate, in the truth table is a column). (C) (2 marks) Compare the final output columns in these two truth tables. Do these two expressions give the same output? Hence, are the 2 expressions equivalent
