## Where is the next state in T flip-flop?

The next state of the flip flop is opposite to the current state when the toggle input is set to 1.

- If toggle input is set to 1 and the present state is 0, the next state will be 1.
- If toggle input is set to 1 and the present state is 1, the next state will be 0.

## How do you derive the excitation table for flip-flops?

In order to complete the excitation table of a flip-flop, one needs to draw the Q(t) and Q(t + 1) for all possible cases (e.g., 00, 01, 10, and 11), and then make the value of flip-flop such that on giving this value, one shall receive the input as Q(t + 1) as desired.

**What is state table and state diagram?**

The state diagram is the pictorial representation of the behavior of sequential circuits, which shows the transition of states from the present state to the next state. What is state table? The state table is a table that describes how the sequential circuits behave for the input variables and state variables.

**What is toggle state in JK flip flop?**

The J-K flip-flop has a toggle mode of operation when both J and K inputs are high. Toggle means that the Q output will change states on each active clock edge.

### What is T latch?

The T latch can be formed whenever the JK latch inputs are shorted. The function of T Latch will be like this when the input of the latch is high, and then the output will be toggled.

### How many stable states a flip-flop has?

two stable states

In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs.

**What is the truth table and characteristic equation for T flip-flop?**

Flipflops to be considered are: SR Flipflop. JK Flipflop. D Flipflop….Truth Tables, Characteristic Equations and Excitation Tables of Different Flipflops.

S | R | Q(t+1) |
---|---|---|

0 | 0 | Q(t) |

0 | 1 | 0 |

1 | 0 | 1 |

1 | 1 | Invalid inputs |

**How many states does a flip-flop have?**

A flip flop is an electronic circuit with two stable states that can be used to store binary data. The stored data can be changed by applying varying inputs. Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems.
