Document Summary

Module 3 d : clocked synchronous state machine. We are going to talk about two different state machine structures known as moore and mealy. State machine is a generic name given to sequential circuits. Clocked indicates that the flip flops employ a clock input. Synchronous meaning that all the flip flops change state together. Analysis means to analyze the behavior using steps : constructing the ps ns equations, drawing the state transition diagram and the timing chart. Moore machine : outputs are a function of the current state the outputs are a function of a state variable not the inputs. In a mealy machine : there are 2 paths : the outputs are a function of the current state and the current inputs both you can see diagrams of both : {refer to slides 171 and 172 of the ppt notes for module 3 for the block figures of both state machines. }
