Digital Circuits Lecture - Summary - Finite State Machines

Explore finite state machines (FSMs) in digital circuits through this comprehensive lecture summary. Learn the step-by-step process of designing FSMs, starting with problem understanding and progressing through initial diagram creation, state minimization, and state assignment. Discover how to choose appropriate flip-flops, implement D flip-flops, and analyze outputs. Examine simulation results and gain insights into schematic notation. Compare Mealy and Moore machines, understanding their differences and applications. Delve into state transition diagrams and tables for both types of FSMs. Conclude with an introduction to Gray coding and its relevance to initial state assignment in digital circuit design.
