In a CMOS processing system, a bus system is used in a data processing process. The data received by a computer is stored in three different levels of storage. A level sensor in each storage produces a “no space of storage” message to the user display when the level of data/information in the storage in below a specified point. Illustrate a logic diagram for monitoring the level of storage based on the following Boolean Expression: 

X= AB + ABC + A B C +AC 

Then, you are required to simplify the Boolean expression in the simple Arithmetic equation and redesign a new logic diagram with the Truth Table. You are required to indicate all the working steps and marks are given accordingly.
