'11. Four big tanks in a chemistry industry contains different liquids being heated. There are liquids level sensors in order to detect always when the level in the tank A ou B goes above certain level: The temperature sensors in the tanks C and D detect when the temperature of one of them goes below determined limit:
Suppose that the outputs A and B will be LOW, with the satisfactory level and it will be HIGH, when the level goes too high: Also, the outputs Cand D of the temperature sensors will be LOW, with the satisfactory temperature; and it will HIGH, when it gets too low:
Project a simplified logic circuit that detects always that a level in the tank A or B gets high, at the same time that the temperature in one of the tanks C or D gets too low.'
