In an industrial plant, two tanks, Tank A and Tank B, are connected to the same output valve (V). A sensor in each tank detects when the tank is full A = logic 1; B = logic 1). When the plant is not being operated manually (M = logic 0), then the valve must open (V = logic 1) when either Tank A is full or Tank B is full, but not both. What is the Boolean logic expression for %3D %3D %3D when the valve should be opened? OV = M· (A+ B) Ov = M + A+ B O V = MAB O v = M (AB+ AB)
