T 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 D flip-flop

D TRUTH TABLE drawio

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

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

EXC T drawio

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

To implement a D flip-flop from T flip-flop is as follows

T TO D COMB drawio

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

In this case the given flip-flop is T.

Therefore, write the Boolean expression for T from the conversion table using K-Maps.

K-Map for T:

Expression for T would be

EXPRESSION drawio

Step 5: Draw the circuit for implementing D flip-flop from T flip-flop

For this, connect the input of the T flip-flop to the circuit of the Boolean expression for T.

Therefore, the circuit would be:
