This video explains the step by step design of the Finite State Machine (FSM). The procedure of designing the Mealy type FSM is explained by the example of 1001 Sequence Detector.
In this video, the design of both Overlapping and Non-overlapping Sequence Detector is explained along with the Simulation of the Designed Circuits.

The steps of designing the Finite State Machine :
1) Define the purpose of the Machine in simple words or in form of Block Diagram. Define the inputs and outputs of the FSM. It should be realizable using finite number of memory elements.
2) Draw a State Transition Diagram
3) Draw a State Table
4) Remove the redundant states from the state table
5) Select the Type of Flip-Flop (D, T, JK or SR) and draw the excitation table
6) Find the Boolean Function for each flip-flop in terms of state variables and inputs.
In a same manner, also fine the output Boolean Function.
7) Draw and Implement the Logic Circuit.

Thanks for explaining these concepts in great detail. Question :- Is the sequence generator made with the FSM different from the one with the shift registor?
@ALLABOUTELECTRONICS

Yes both are different one.

You are an absolute legend. Also I want to ask,what would we do if we were to use a JK flip flop for the implementation. How do we figure out how many flip flops to use?

hello sire, how to know what to put in the preset and clear of the flip flops in the simulator?
@ALLABOUTELECTRONICS
@ALLABOUTELECTRONICS 9 місяців тому
Generally, the preset and clear inputs of the flip-flop are active low. Meaning that when 0 is applied as an input then it will get activated. So, when we want to clear the flip-flops then we should make clear input 0. And we want to make them inactive, we should apply 1. This is valid, considering the inputs are active low. If they are active high, then you need to do other way around. I hope, it will clear your doubt.

hi, I tried following all the steps for another string but If I try to simulate the circuit It never gives output 1...any chances I can contact you somewhere to share my work?

Perhaps, you might have made some error during the design steps. You may contact me via mail.

How did you determine the Q1+ and Q0+ ???????
@ALLABOUTELECTRONICS
@ALLABOUTELECTRONICS 4 місяці тому
It is written from the state table. For example, when x=0 and present state is 00 then next state is also 00. ( see the left table). According to that, in the second table ( right one), the Q1+ and Q0+ is 00. Similarly when x=1, then next state is 01. So in the second table in the fifth row Q1+ and Q0+ are 0 and 1 respectively. I hope, it will clear your doubt.
