Two teachers (A, B) will grade two questions in an exam. Tacher A will grade question 1 which is 60 points. Teacher B will grade question 2 which is 40 points. Teachers can give the points as below: Teacher A → 0, 20, 40, 60 Teacher B → 0, 20, 30, 40 If a student takes 60 or more, he/she will be successfull. Design the circuit by using ROM

4. Two multiplexers are connected as shown below. The inputs (A, B, C) and the output F are 4-bits and (D and E) are one-bit. The numbers inside the multiplexers correspond to the value of the selectors D and E which will decide which input A, B or C will pass to the output F (For example, If D = 0 and E = 0 then C will be selected to pass to F).

There are two major courses A and B, and two minor courses C and D in a department. A student can graduate if he or she passes: Both the major courses A and B or One major course and both minor courses C and D. Design a circuit to determine if the student can graduate or not. Part a: Determine the truth table. Hint: Use the name of the courses as the input variables of your truth table. i.e., A, B, C, D. Variable A is 1 if a student passes course A, otherwise 0. Part b: Write the function in sum of minterms form and simplify using K-map. Part c: Implement the simplified function on proteus and attach its screenshot. Note: Use 4-bit binary of your roll number’s last digit to show output in the screenshot. Part d: Implement the simplified function on virtual breadboard and attach its screenshot. Note: Use 4-bit binary of your roll number’s last digit to show output in the screenshot.
