Four large tanks at a chemical plant contain different liquids being heated. Liquid-level sensors are being used to detect whenever the level in tank A or tank B rises above a predetermined level. Temperature sensors in tanks Cand D detect when the temperature in either of these tanks drops below a prescribed temperature limit. Assume that the liquid-level sensor outputs A and Bare LOW when the level is satisfactory and HIGH when the level is too high. Also, the temperature-sensor outputs C and Dare LOW when the temperature is satisfactory and HIGH when the temperature is too low. Design a logic circuit that will detect whenever the level in tank A or B is too high at the same time that the temperature in either tank Cor tank D is too low.
