SR flip flop to JK flip flop - mbits-mirafra/digitalDesignCourse GitHub Wiki

Step 1: Write the truth table of the required flip-flop

Here the required flip-flop is JK flip-flop

Step 2: Write the excitation table of the given flip-flop

In this case the given flip-flop is SR flip-flop

Step 3: The conversion table, which is a combination of the truth table and excitation table

To implement a JK flip-flop from SR flip-flop is as follows

Step 4: Find the Boolean expressions for the inputs of the given flip-flop

In this case, the given flip-flop is SR.

Therefore, write the Boolean expressions for S AND R from the conversion table using K-Map.

K-Map for S:

Expression for S would be

K-Map for R:

Expression for R would be

Step 5: Draw the circuit for implementing JK flip-flop from SR flip-flop
