18.5 STATE TABLES
The state table representation of a sequential circuit consists of three sections, labelled as the present state, next state and the output. The present state designates the state of flip-flops before the occurrence of a clock pulse. The next state shows the state of flip-flops after the clock pulse, and the output section lists the value of the output variables during the present state.
18.5.1 State Diagrams
In addition to the graphical symbols, tables or equations, counter can also be represented pictorially by a state diagram. In this diagram, a state is represented by a circle, and the transition between the states is indicated by directed lines (or arcs) connecting the circles. An example of a state diagram is shown in ...
