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.
