Prerequisite: Conversion of flip-flops

## Example 1: Conversion of SR flip-flop to D flip-flop

Solution:

Step 1: Truth Table of the required flip-flop (D flip-flop) is given as: Step 2: Using the excitation of given SR flip-flop, find the SR values, and complete the conversion table as: Step 3: Solving K-Map for S and R values separately to get the Boolean expression. Step 4: Making the logic circuit to implement the Combinational circuit using obtained Boolean expressions from K-Map. ## Example 2: Conversion of D flip-flop to T flip-flop

Solution:

Step 1: Truth Table of the required flip-flop (T flip-flop) is given as: Step 2: Using the excitation of a given D flip-flop, find the D values, and complete the conversion table as: Step 3: Solving K-Map for D value to get the Boolean expression. Step 4: Making the logic circuit to implement the Combinational circuit using obtained Boolean expressions from K-Map. ## Example 3: Conversion of JK flip-flop to SR flip-flop

Solution:

Step 1: Truth Table of the required flip-flop (SR flip-flop) is given as: Step 2: Using the excitation of given JK flip-flop, find the J and K values and complete the conversion table as: Step 3: Solving K-Map for J and K values separately to get the Boolean expression. Step 4: Making the logic circuit to implement the Combinational circuit using obtained Boolean expressions from K-Map.
