## What is state minimization in digital electronics?

State Reduction (State Minimization) By reducing or minimising the total number of states, the number of flip-flops required for a design is also reduced. For example if a finite state machine drops from 8 states to 4 states, only two flip-flops are required rather than three.

### What is the significance of reduction of state tables?

The reduction of the number of flip-flops in a sequential circuit is referred to as the state reduction problem. State-reduction algorithms are concerned with procedures for reducing the number of states in a state table, while keeping the external input-output requirements unchanged.

#### How can we reduce the state table?

To minimize the number of states, we will identify “equivalent states” and eliminate any redundancy found. Two states are equivalent if they have equivalent next states and the same output for each possible input condition.

What is an implication chart?

Implication charts are a common way of reducing an FSM. It works by finding states that have identical transitions to each other. It is a graphical method suitable for fast computation by hand.

How does state Reduction help to design a sequential circuit?

The number of states in a sequential circuit is closely related to the complexity of the resulting circuit. It is therefore desirable to know when two or more states are equivalent in all aspects. The process of eliminating the equivalent or redundant states from a state table/diagram is known as state reduction.

## What is fan in and fan out?

Fan-in refers to the maximum number of input signals that feed the input equations of a logic cell. Fan-out refers to the maximum number of output signals that are fed by the output equations of a logic cell.

### What is state table in digital electronics?

State Table: State table is a tabular representation of the behavior of a sequential logic circuit. For a given input and present state of a circuit, it gives the output and the next state of the circuit. It is created using the characteristic table for the appropriate flip-flop.

#### What does a state table indicate?

In automata theory and sequential logic, a state-transition table is a table showing what state (or states in the case of a nondeterministic finite automaton) a finite-state machine will move to, based on the current state and other inputs. A state-transition table is one of many ways to specify a finite-state machine.

What is state table 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.
