4. In a certain chemical processing plant, a liquid chemical is used in a mamifacturing process. The chemical is stored in three different tanks (x, y, z). A level sensor in cach tank produces a HIGH voltage (logic 1) when the level of chemical in the tank drops below a specified point. Design a digital circuit that monitors the chemical level on all the three tanks and indicate a status (or give alarm) on the following conditions; (the level on tank y and tank z drops below the specified point) OR (the level on tank x and tank z drops below the specified point) OR (the level on all the three tanks drops below the specified point). (4 pts) a. Construct the truth table for the function, F(x, y, z) representing the status (alarm) indicator b. Write the function as sum of minterms and product of maxterms. Please give your answers as a function of x, y, and z. c. Determine the simplified sum of products (SoP) form functional representation of F(x, y, z) and the draw the logic circuit diagram for the simplified function
