Fundamental Hardware Elements of Computers: Boolean gate combinations

 Exercise: Logic gate combination outputs For the following logic gate combinations work out output Q for each: Answer: Answer: Answer: This equation can be simplified to equal ${\displaystyle A.B}$, as ${\displaystyle B.B=B}$, we'll find out why this is the case in the simplifying boolean equations section coming up Answer: This equation can be simplified to equal 0 (always false), as ${\displaystyle {\overline {A+B}}.A=0}$, we'll find out why this is the case in the simplifying boolean equations section coming up Answer:
