Question

1.What are the similarities between a characteristic table, and an excitation table?

2.What are the similarities between a truth table and a state table?

Answer 1

Answer:

1. Excitation table is used for design of flip-flops and counters. A characteristics table has the control input (D or T) as the first column, the current state as the middle column, and the next state as the last column.

2. Where truth tables are used to describe combinatorial circuits, state tables are used to describe sequencial circuits. A state table looks similar to a truth table, except that in addition to the inputs, the left part of the table also contains the values of the outputs.

Answer 2

Characteristics, Excitation, Truth and State Tables

Explanation:

Characteristics Table:

A Characteristics Table defines the next state of flip-flop in terms of flip-flop input and current state.

Excitation Table:

An Excitation Table defines the flip-flop input variable as a function of the current state and next state.

Truth Table:

A Truth Table is a mathematical table used to determine if a compound statement is true or false.

State Table:

A State Table defines the behavior of the sequential function.

All the tables are similar in that they have an input and a output column.
