3. Implement and Analyze Sequential Circuits, Including State Machines
Sequential circuits are defined by their reliance on both current inputs and past states, facilitated by memory elements such as flip-flops. This chapter discusses different types of sequential circuits, including finite state machines (FSMs), and outlines the design steps necessary to create these circuits. Key concepts are reinforced with practical examples and implementation strategies that employ combinational logic and various types of flip-flops.

Key Concepts
- -- Sequential Circuits
- Type of circuit whose output depends not only on current inputs but also on previous states, utilizing memory elements.
- -- Finite State Machine (FSM)
- A computational model that consists of a finite number of states and includes input-driven transitions between these states, along with outputs.
- -- FlipFlop
- A basic memory element in digital electronics, used to store binary information based on inputs and clock signals.
- -- Synchronous and Asynchronous Circuits
- Synchronous circuits rely on a common clock signal for state changes, whereas asynchronous circuits change states based on input transitions.
