All 9 questions on Boolean Algebra and Logic Circuits, as a list
- June 2024, Paper 3, Q6(a) (3 marks): Complete the truth table for the given logic circuit. Show your working. Working space A B C P Q R S Z 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 [3]
- June 2024, Paper 3, Q6(b) (2 marks): Write the Boolean expression that corresponds to the logic circuit as a sum-of-products. Z = [2]
- June 2024, Paper 3, Q6(c)(i) (2 marks): Complete the Karnaugh map (K-map) for the Boolean expression: A.B.C + A.B.C + A.B.C + A.B.C + A.B.C + A.B.C BC 00 01 11 10 A 0 1 [2]
- June 2024, Paper 3, Q6(c)(ii) (2 marks): Draw loop(s) around appropriate group(s) in the K-map to produce an optimal sum-of-products. [2]
- June 2024, Paper 3, Q6(c)(iii) (1 mark): Write the Boolean expression from your answer to part (c)(ii) as a simplified sum-of-products. [1]
- Specimen, Paper 3, Q3(a) (2 marks): Complete the Boolean expression that corresponds to the following truth table. INPUT OUTPUT A B C X 0 0 0 0 0 0 1 0 0 1 0 0 0 1 1 1 1 0 0 0 1 0 1 0 1 1 0 1 1 1
- Specimen, Paper 3, Q3(b)(i) (1 mark): Complete the Karnaugh map (K-map) for the truth table given in part (a). AB 00 01 11 10 0 C 1 [1] The K-map can be used to simplify the function in part (a).
- Specimen, Paper 3, Q3(b)(ii) (2 marks): Draw loop(s) around appropriate groups of 1s to produce an optimal sum-of-products. [2]
- Specimen, Paper 3, Q3(b)(iii) (2 marks): Using your answer to part (b)(ii), write the simplified sum-of-products Boolean expression. X = [2]
