CONVERSION OF T-TYPE FLIP FLOP TO D-TYPE FLIP FLOP
Step 1: Draw the excitation tables for the conversion
External Flip Flop Input | Present State | Next State | Internal Flip Flop Input |
---|---|---|---|
D | Qn | Qn+1 | T |
0 | 0 | 0 | 0 |
0 | 1 | 0 | 1 |
1 | 0 | 1 | 1 |
1 | 1 | 1 | 0 |
Step 2:Draw the K-Map for the internal flip flop inputs in terms of Qn and D
D \ Q | 0 | 1 |
---|---|---|
0 | 0 | 1 |
1 | 1 | 0 |
Thus,from the above K-Map we get the expression for internal flip flop input,T;which is:
T =$\bar{D}Q+D\bar{Q} = D⊕Q$
