A burglar alarm is an electronic device that emits a loud noise when someone attempts to make unauthorized entry to a building or other premises.
Here ‘a’ , ‘b’ and ‘c’ are three inputs. ‘a’ and ‘b’ as a switch or ‘c’ as a window. When c=0 its mean window is closed and when c=1 its mean window is open. So when window is open the family member enter into house by giving code 0-1 and at this stage alarm not beat but all others combinations with ‘1’ get the alarm on.
