Karnaugh Map is used to simplify Boolean algebra expressions.

  • It is a graphical technique for simplifying Boolean expressions.
  • It is also known as K-map.

An excitation table is a tabular representation of the inputs and outputs of a digital logic circuit, typically used for designing sequential logic circuits, such as flip-flops or latches.

  • It shows the relationship between the current state and the next state of the circuit, based on the inputs and current state.

A state table, also known as a state transition table or state diagram, is a representation of the different states and transitions of a digital system or circuit.

  • A state table typically consists of two main parts: the current state and the next state.
  • The current state represents the current state of the system, while the next state represents the state that the system transitions to based on the input conditions.
