Sequential Logic Design

Chapter 3 addresses sequential logic, in which the outputs depend on both current and past inputs. Registers are common sequential elements that remember their previous input. Finite state machines, built from registers and combinational logic, are a powerful way to build complicated systems in a systematic fashion. We also study timing of digital systems to analyze how fast the systems can operate.
