17Mealy Glitches Glitiches occur because x changes before the next rising clock edgeS0S2S1S3
18General Structure of a Mealy Machine Output depends on input as well as the stateThe circuit is in. (variable: state)Synchronize the input with clock when using Mealy machine.
19Moore MachineOutput depends on the state, but not the input.
20Synthesis of Sequential Circuit Start with a state diagramAssign Binary Values to the States
21State Diagram for Sequence Detector Problem statement:Design a circuit that detects a sequence of three or more consecutive 1’s in a string of bits coming through an input line
22State Diagram of the Word Description Start with S0.if input is 0, stay in S0.if input is 1, go to S1.Once in S1if input is 1, go to S2.if input is 0, go to S0.Once in S2if input is 1, go to S3.Once in S3,if input is 1, stay in S3, set output to 1.Output is 1 when the circuit is in S3, 0 otherwise.
23Assign Binary Value to the States 1234567Use two flip-flops to represent states.Let x be the inputAnd y be the output
