Ring Counter
A ring counter is a Shift Register (a cascade connection of flip-flops) with the output of the last flip flop connected to the input of the first.

whose outputs depend on only the present state
whose output depends on the present state as well as the present input.

3. state diagram
algebraic expression that specifies the condition for a flip-flop state transition
The information available in a state table can be represented graphically in the form of a state diagram. In this type of diagram, a state is represented by a circle, and the transitions between states are indicated by directed lines connecting the circles.
State table
The time sequence of inputs, outputs, and flip-flop states can be enumerated in a state table (sometimes called transition table)

5. State Equation A(t+1) = A(t) x(t) + B(t) x(t) B(t+1) = A`(t) x(t)
A state equation is an algebraic expression that specifies the condition for a flip-flop state transition. The left side of the equation with (t+1) denotes the next state of the flip-flop one clock edge later. The right side of the equation is Boolean expression that specifies the present state and input conditions that make the next state equal to 1.
Y(t) = (A(t) + B(t)) x(t)`

7. State Diagram 1/0 : means input =1 output=0
The information available in a state table can be represented graphically in the form of a state diagram. In this type of diagram, a state is represented by a circle, and the transitions between states are indicated by directed lines connecting the circles.
1/0 : means input =1
output=0
