# What is the use of counter excitation table?

## What is the use of counter excitation table?

The excitation table is very useful to design counters, frequency divider circuits that is required for digital communication.

**What is meant by excitation table?**

In electronics design, an excitation table shows the minimum inputs that are necessary to generate a particular next state (in other words, to “excite” it to the next state) when the current state is known.

**What is the difference between truth table and excitation table?**

The truth table maps current states and inputs to outputs (on a circuit level). An excitation table is used when a particular gates needs a particular output in order to implement the truth table.

### Why we use excitation table in flip-flop?

The excitation table has the minimum inputs, which will excite or trigger the flip flop to go from its present state to the next state. It is derived from the truth table. Generally, the operation of each flip flop is explained with the help of the truth table.

**What is excitation table of D flip-flop?**

Excitation table: Shows what input is necessary to generate a given output. Different view of flip-flop operation. Inputs: Q, Q. + Output: control (D or T)

**What is the difference between a truth table and an excitation table of a flip-flop?**

The truth table has all the input combinations, for which the flip flop reacts to produce the next state output. The excitation table consists of two columns for present state(Qn) and next state(Qn+1) and one or two column for each inputs. The input columns depend on the type of the flip flop.

## Is state table and excitation table same?

Answer. A state table defines the behavior of the sequential function. Truth table gives relation between inputs and outputs. Excitation table is used for design of flip-flops and counters.

**What is excitation table SR flip-flop?**

The excitation table of any flip flop is drawn using its truth table. What is excitation table? For a given combination of present state Qn and next state Qn+1, excitation table tell the inputs required. Qn.

**What is meant by excitation and excitation table?**

### What is counter in digital electronics?

In digital logic and computing, a counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock. The most common type is a sequential digital logic circuit with an input line called the clock and multiple output lines.

**What is excitation table of J-K flip-flop?**

For JK flip flop, the excitation table is derived in the same way. From the truth table, for the present state and next state values Qn = 0 and Qn+1 = 0(indicated in the first and third row with yellow color), the inputs are J = 0 and K = 0 or 1.

**What is use of state table?**

A state table is nothing more than a truth table that specifies the requirements for the next-state logic, with inputs coming from the state register and from outside the circuit. The state table lists all required states, and all possible next states that might follow a given present state.
