Logic Circuit for Logic function & Logic function from Logic circuit

At the end of this lesson-

1. You will be able to implement any function.

2. You will be able to determine function from any circuit. 

 

Go for Bangla Version

 

Implementation of any function:

• The function may need to be implemented with only basic gates.
• The function may need to be implemented with only universal gates.
• The function may need to be implemented using any type of gates.
• After simplifying the function, It may need to be implemented by basic or universal gates.

 

The following rules or sequences are followed to implement the function using the basic gates:

• If the function needs to be simplified, it needs to be simplified first.
• A common line has to be drawn for each of the variables in the function.
• From the left of the function the basic operations( NOT, AND, OR)  must be done respectively. In this case the parentheses “()” must be given the priority.

 

Example-1: Implement the following function using only basic gates.

Solution:

 

 

 

 

 

 

 

 

 

 

Example-2: Implement the following function.

Solution:  

 

Logic function from Logic Circuit:

• It may need to simplify logic functions from logic circuit.
• Simplified functions from a logic circuit can be implemented by  basic or universal gates.

 

Example-1: Determine the simplified function from the following circuit.

Solution:

 

Example-2: Implement the simplified function of the following circuit.

Solution:  

Now implement the above simplified function-
