Design a combinational circuit that outputs 1 when the restrictions given in the below scenario are met. The output will be 0 otherwise.
Consider a strong room at a university where question papers are stored. Entry to this room is restricted to specific employees of the university. The rules for entering the room are:
Only the exam superintendent can enter alone
Head of the department can enter only if he is accompanied by the exam superintendent
Course leader can enter only if he is with the exam superintendent or head of the department
Tutor can enter the room only if he is accompanied by the exam superintendent
B.1.1 Write the truth table for the combinational circuit described above. B.1.2 Express the behaviour of the circuit in the canonical Sum of Product (SoP) form.
B.1.3 Reduce the above SoP expression to the minimized form using K-Map.
