In the Figure $3,$ a database error $($unstable display of the saving's balance$)$ is reported when both Mr$.$ John and his wife are trying to withdraw amount from John's account at the same time for long duration. If either John or his wife withdraw individually, transaction is successful and respected balance is displayed. When none is operating, the balance remains the same.

a$)$ Outline the remedies to address the Race around Condition.

$(3$M$,$ BTL$-2,$CO$3,$ CO$4)$

b$)$ Design the logic circuit for the above scenario using universal gates.$(3$M$,$BTL$-3,$CO$3,$ CO$4)$

c$)$ Analyse its behaviour with help of truth table, excitation table and timing diagram.
