Daniel Mihai Problem 2.2 We can design the upper circuit in order to determine if the player lost. If we set the D input of the D flip-flop to 1 and maintain it constant, AND the signals from all the cells of a battleship and set the Q output to be 0 initially, once one battleship is destroyed all the signals from its cells will be 1, hence the result of the lower AND gate will be 1. As soon as we have D and E 1,

Unformatted text preview: the output of the flip-flop will change to 1. Even if in another turn the E input of a flip-flop will be 0, Q will still be 1, because in this state( E=0 and D=1) the value of Q is hold (so, once a battleship is destroyed, the output of the respective flip-flop will change to 1 and will remain this way, no matter the following turns)....

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
