A bank burglar alarm (B) will activate if it is after banking hours (A) and someone opens the front door (D). The logic level of A is 1 after banking hours and B during banking hours. Also the logic level of the variable D is 1 if the door sensing switch is opened and B if the door sensing switch is closed.
Determine the Boolean expression to activate the burglar alarm.
I'm confused with this statements "The logic level of A is 1 after banking hours and B during banking hours. Also the logic level of the variable D is 1 if the door sensing switch is opened and B if the door sensing switch is closed."
I think there is something wrong with this statement "The logic level of A is 1 after banking hours and B during banking hours." I think the "B" should be "0".
and also in the next statement the "B" should be "0". Is my presumption correct?
If my presumption is right the result would be B = AD which is just an AND gate.
Do you think there might be some clerical error in the problem or am I the one who is wrong?
