- Synchronous sequential circuit of Moore model for analysis.
Step 1: Write the excitation and output functions.
Step 2: Substitute the excitation functions into the characteristic equations for the two flip-flops to get the next-state equations.
Step 3: Convert the next-state equations to next-state maps.
What is synchronous sequential circuit?
Synchronous sequential circuits are digital circuits that use clock signals to determine the timing of their operations.

What is the design of a synchronous sequential circuit requires?
A synchronous sequential circuit is made of flip-flops and combinational gates.
The design of the circuit consists of choosing the flip-flops and then finding the combinational structure which, together with the flip-flops, produces a circuit that fulfils the required specifications..
When given a circuit diagram, the following steps are used to begin the analysis.
1 Determine the inputs and outputs of the circuit. 2 Determine the inputs and outputs of the flip-flops.- Construct the Next State and Output Tables
- Construct the State Diagram
- If possible, identify the circuit
The analysis of synchronous sequential logic circuits is facilitated by the use of state tables which consist of three vertical sections labeled present state, flip flop inputs, and next state. The present state represents the state of each flip flop before the occurrence of a clock pulse.

Circuit that produces time-varying output without having a time-varying input
An autonomous circuit in analogue electronics is a circuit that produces a time-varying output without having a time-varying input .
In digital electronics, an autonomous circuit may have a clock signal input, but no other inputs, and operates autonomously, cycling through a set series of states.
A Moore machine is autonomous if it has no data inputs, the clock signal not counting as a data input.
If a Moore machine has data inputs, they may determine what the next state is, even though they do not affect the outputs of any given state, and this is a non-autonomous circuit.
A synchronous programming language is a computer programming language optimized for programming reactive systems.
Computer systems can be sorted in three main classes: (1) transformational systems that take some inputs, process them, deliver their outputs, and terminate their execution; a typical example is a compiler; (2) interactive systems that interact continuously with their environment, at their own speed; a typical example is the web; and (3) reactive systems that interact continuously with their environment, at a speed imposed by the environment; a typical example is the automatic flight control system of modern airplanes.
Reactive systems must therefore react to stimuli from the environment within strict time bounds.
For this reason they are often also called real-time systems, and are found often in embedded systems.
