Extracted text: Question 4: The ongoing Covid pandemic in the word has scared the authorities at Hazrat Shahjalal International Airport in Dhaka and they have asked the CSE department of BRACU to design a system that would help them to decide what to do with people coming in from African countries that are at risk. The Airport authorities has approved the following specifications for the system: Input (4 variables) F = 1 indicates the passenger HAS FEVER. H = 0 indicates the passenger DOES NOT HAVE a SEVERE HEADACHE. M = 1 indicates the passenger HAS MUSCLE PAIN. A = 0 indicates the passenger DOES NOT HAVE ABDONIMAL (STOMACH) PAIN. Output (3 variables)


Extracted text: Q = 1 indicates the passenger should be quarantined (Kept locked up in a separate area and not let anyone come in contact with him or her so as to prevent COVID from spreading). T= 1 indicates the passenger is at RISK and needs to be tested. G = 1 indicates the passenger is free to go. The Airport authorities has asked us to consider the following points when designing the system: I. A passenger who has FEVER and MUSCLE PAIN and any one of the other two symptoms (STOMACH PAIN or SEVERE HEADACHE) should be QUARANTINED. I. A passenger who has TWO OR MORE symptoms out of the four should be sent for testing. II. A passenger who does not fall in any of the above criteria is free to go. PLEASE NOTE THAT THIS POINTS ARE GIVEN IN ORDER OF PRIORITY .. so 1 HAS THE HIGHEST PRIORITY AND 3 HAS THE LOWEST. a. Using the above specification, prepare a truth table for the system. b. Using 4 variable Karnaugh-Map methods, derive SOP expressions for all of the three outputs.
