You have been hired by an industrial plant that is responsible for recycling plastic, glass and aluminum. All material that is recycled must go through an initial stage that classifies the type of material that enters the plant. For the work of the plant, two requirements are requested that you must consider. 

Requirement 1: To start, a motor must be started that advances a conveyor belt, but, for safety, the belt starts only when the two activation switches are in equal positions. If both switches are on the right or both are on the left, the conveyor belt should activate. 

Requirement 2: the industry has three warehouses where it stores classified products (plastic, glass and aluminum). In each tank there is a sensor that indicates whether it is completely full or still has storage capacity. In addition, there is a panel that shows the status of the deposits in general: 

● Variable L (Light): is set to 1 when no tank is full. 

● Variable M (Medium): is set to 1 when only one tank is full. 

● Variable C (Critical): is set to 1 when 2 or more tanks are full.

 

 

To respond to requirement 1:  Prepare the truth table for the plant lighting control, obtain the logical function of the circuit and simplify the logical function using the postulates of Boolean Algebra. 

To respond to requirement 2:  Prepare the truth table for the alert control of the company's deposits. 

 Build the Karnaugh Map for the 3 outputs or alerts of the circuit: V, N and R, and make the groupings. 

Simplify the groupings and obtain the circuit equation. 

Note: For this task, the design of circuits with logic gates is not required. 

With the answers to the activities proposed above, you must complete a report according to the following format: 

a) Introduction. 

b) Development of assigned activities. 

c) Conclusion. 

d) Bibliographic references.
