It simplifies operation by connecting the J and K inputs together, treating them as a single input (T).
The T flip-flop either toggles its output (Q) or maintains its current value based on the T input and the clock pulse.
Functionality:
T = 0: On a clock pulse, the flip-flop holds its current value. Q(t+1) = Q(t). No change occurs.
T = 1: On a clock pulse, the flip-flop toggles its output. Q(t+1) = NOT Q(t). The output inverts.
Truth Table:

Key Points:
The "T" in T flip-flop stands for "Toggle".
The clock pulse is essential for the T flip-flop to change state (either toggle or hold). The value of T only determines what happens when the clock pulse occurs.
T flip-flops are useful for building counters and frequency dividers because of their toggling behavior.
