Question 1 (a) Logic is basically human reasoning that tells us if certain proposition or declarative statement is true. The president of our school wants to help lecturers and student by give them personal insurance cover, and the policy of the said stated insurance is as follows. The insurance policy will be issued to a student or a lecturer, if he is: (i) A married female / male lecturer of 22 years or more, or (ii) A female /male student under 22 years, or (iii) A married male / female student under 22 years and who has not been involved in a car accident, or (iv) A married male / female staff who has been involved in a car accident, or (v) A married male / female lecturer of 22 years old or above and who has not been involved in a car accident. Kindly design a combinational logic circuit using NAND gates only which can issue the insurance policy to applicants.
Question 1
(a) Logic is basically human reasoning that tells us if certain proposition or declarative statement is true.
The president of our school wants to help lecturers and student by give them personal insurance cover, and the policy of the said stated insurance is as follows.
The insurance policy will be issued to a student or a lecturer, if he is:
(i) A married female / male lecturer of 22 years or more, or
(ii) A female /male student under 22 years, or
(iii) A married male / female student under 22 years and who has not been involved in a car accident, or
(iv) A married male / female staff who has been involved in a car accident, or
(v) A married male / female lecturer of 22 years old or above and who has not been involved in a car accident. Kindly design a combinational logic circuit using NAND gates only which can issue the insurance policy to applicants.
(b) Discuss in detail, the working of Full Adder logic circuit and extend your discussion to explain a binary adder, which can be used to add two binary numbers.
(c ) With relevant logic diagram and truth table explain the working of a two input EX-OR gate.
