2.4 Draw the truth table of a 2-input XOR gate. (2) QUESTION 3. [30] 3.1 (a) Convert following SOP (Sum of Products) Boolean expression to a truth table: (5) X(ABC) ABC+ A B+ABC (b) Write the Boolean expression for the following Logic circuit: ES BA (5) 3.2 (a) Discuss the Positive edge triggered R-S and also provide its logic circuit. (8) (b) Draw the truth table of the Positive edge triggered R-S flip flop. (4) 3.3 Answer the following two questions: (a) Apply Demorgans theorem and draw the equivalent circuit in which OR gate operates identical to the NAND gate with four inputs. (b) Apply Demorgan's theorems to the expression: X = (A + B) (AC) (4) (4) 2.4 Draw the truth table of a 2-input XOR gate. (2) QUESTION 3.
