Consider the circuit A B B F a. Write the logic function that corresponds exactly (gate-for-gate) to the circuit. (3 marks, one for each gate) b. Write out the truth table for the circuit, considering all possible input combinations. (4 marks, one for each entry in the truth table) c. Identify the single gate that performs the same operation as the circuit. (2 marks) d. Describe, in plain English, how the circuit operates to get the desired result. i.e. what does each gate do to contribute to the result. (3 marks)
