I need State diagram 11001

[ digital logic design]​

Answer 1

Answer:

State Diagrams and State Tables

Fundamental to the synthesis of sequential circuits is the concept of internal states. At the start of a design the total number of states required are determined. This is achieved by drawing a state diagram, which shows the internal states and the transitions between them.

All states are stable (steady) and transitions from one state to another are caused by input (or clock) pulses. Each internal state is represented in the state diagram by a circle containing an arbitrary number or letter ; transitions are shown by arrows labelled with the particular input causing the change of state. In the case of pulse outputs the transition arrows are also labeled with the output associated with the input pulse. This will be made clear by examples given below.

As a simple example, consider a basic counter circuit that is driven by clock pulses (x) and counts in the following decimal sequence: 0,1,2,3,0,1,2,3,0,1,2, etc.

It follows that there are four unique states yielding the following state diagram:

It follows that since there are 4 unique states then two flip-flops or secondaries are required in the design. Each flip-flop output can take on the value 0 or 1, giving four possible combinations.

It should be pointed out at the outset that once the state diagram and corresponding state table are derived from the given specification, the design procedure that follows is relatively straightforward.
