(b) Mr. jojo, lives in a four-flat house, the conditions of the lighting system was
very bad and he needs help. He wants the design to be as follows, a
combinational circuit that controls the ceiling lights in my downstairs hallway,
which has three wall switches: one at the front door (A), one at the back door
(B) and one in the family room (C). When I walk in the front door, the ceiling
lights are off, the A switch is ON and both the B and C switches are OFF, From
these initial conditions, changing the position of any switch should turn the
lights on; changing the position of any switch (again) should turn the lights off,
(c) What is the purpose of Karnaugh map and its limitations?
