Conversion of S-R Flip-Flop into T Flip-Flop

Prerequisite - 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:
