Prerequisite – Flip-flop

**1. J-K Flip-Flop:**

J-K flip-flop is the gated version of Sr flip-flop with an addition of extra input i.e. clock input. It prevents invalid output condition when both the inputs are at the same value.

**2. T Flip-Flop:**

T flip-flop means Toggle flip-flop. It changes the output on each clock edge and gives an output which is half the frequency of the signal to the input.

**Conversion of J-K Flip-Flop into T Flip-Flop:**

**Step-1:**

Construct the characteristic table of T flip-flop and excitation table of J-K flip-flop.

**Step-2:**

Using K map, find the boolean expression for J and K in terms of T.J = T K = T

**Step-3:**

Construct the circuit diagram for the conversion of J-K flip-flop into T flip-flop.
