Question 1

What is the T flip-flop truth table?

Accepted Answer

The T (Toggle) flip-flop truth table: When T=0, the output Q stays the same (holds). When T=1, the output Q toggles (flips) to the opposite state on each clock edge. So: T=0 → Q(next)=Q; T=1 → Q(next)=Q' (complement).

Question 2

How does a T flip-flop toggle?

Accepted Answer

When T=1 and a clock edge occurs, the output changes from 0→1 or 1→0. Each clock pulse with T=1 causes the output to 'toggle' or flip. This makes T flip-flops perfect for building counters and frequency dividers.

Question 3

How do you make a T flip-flop from a JK flip-flop?

Accepted Answer

Connect both J and K inputs together and use that as the T input. When J=K=0, output holds. When J=K=1, output toggles. This converts a JK flip-flop into a T flip-flop.

Question 4

What is the T flip-flop used for?

Accepted Answer

T flip-flops are primarily used for: binary counters (each stage divides frequency by 2), frequency dividers, clock divider circuits, and toggle switches in digital systems. They're essential for counting applications.
