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
