1. In a certain chemical-processing plant, a liquid chemical is used in a manufacturing
process. The chemical is stored in three different tanks. A level sensor in each tank
produces a HIGH voltage when the level of chemical in the tank drops below a
specified point. A circuit that monitors the chemical level in each tank and indicates
when the level in any two of the tanks drops below the specified point was designed.
The designed solution is depicted in the following figure. Assemble the designed
digital circuit and verify its operation by filling the beneath truth table. Use switches to
simulate the operation of the level sensors.
