Flip-flop
Here, we will discuss the process of conversion of S-R Flip-Flop into a T Flip-Flop using an example.
Rules for conversion:
- Step-1:
Find the characteristics table of required flip-flop and the excitation table of the existing (given) flip-flop.
- Step-2:
Find the expression of given flip-flop in terms of required flip-flop using K-map.
- Step-3:
Find the circuit diagram of required flip-flop.
S-R Flip-Flop to T Flip-Flop:
Following is the characteristics table of T flip-flop and excitation table of S-R flip-flop.

Now, using K-map we get the expression for of S & R in terms of T.

S = TQn' &
R = TQn
Therefore, the circuit diagram for conversion of S-R flip-flop into T flip-flop is:
