In a beverage processing plant, a XYZ product is filled in different size bottles. To maintain the standard of the filling plant, the plant is equipped with a level-based alarm system. The system consists of a sensor, which return logic ‘1’ in case of filled bottle and logic ‘0’ in case of low-level filling or empty bottle. The system is also equipped with a negative logic alarm system.  Now, being a design engineer of the beverage processing plant, you need to design a system which detects four consecutive low-level filled/empty bottles and activate the alarm. For designing the system, you are available with JK-Flip Flops and basic logic gates (i.e. AND, OR and NOT).
