The 16 fundamental logical operators

[Jerry Wickey]

There are only 16 fundamental logical operators which describe the fundamental relationship between any two arguments. That is if A is true and B is false then C is false. This is consistent with the logical operator AND, but it is also consistent with the logical operator NOR. The difference between the two lies in their response to the other permutations of A and B.

 

Can you use the logical operator NOR to describe the relationship between the sensors and actuators in this simulation of a swinging ball?

 

Use three NOR gates to connect the sensors to the actuator so that the pin ball is launched upwards at exactly the time needed for the swinging soccer ball to push it out of the way. If you do it right, the pin ball will fall back down and be launched again at the right time every time.
