I suggest to completely rework this and split into at least two lectures and add more examples. I felt rushed and confused and till this point I was constantly ahead in your lectures.

To all those wondering about step 6 No specific reason for using T flip flop. Implementation using D flip flop is easy because next state is same as data input and implementation using JK flip flop takes time, maybe that's why i used T.

The state diagrams discussed in this video remind me of Caley diagrams used in group theory. A group is the fundamental object in the study of abstract algebra. We can construct a group by first identifying a set of elements. We then form all possible permutations of this set, and assign a unique symbol to each permutation. The collection of symbols representing permutations is called a group if there exists a rule for composing any two elements of the group. The rule must follow a few axioms, but this information is not necessary for you to understand my point. The behavior of a group can be summarized in two ways. We may create a composition table or a Caley diagram. The composition table looks exactly like the multiplication table we all grew up memorizing in elementary school. The Caley diagram looks EXACTLY like the state diagrams used to describe the behavior of a sequential circuit. In fact, I am 100% sure that the state diagram in this video could be used to describe the behavior of a group in abstract algebra. My conjecture is that there is a structure preserving relationship (isomorphism) between state diagrams and Caley diagrams. I find this idea extremely tantalizing because it establishes an intimate and fundamental relationship between computer science and abstract algebra. I wonder if this idea might be extended to conclude that there exists a group (field, ring, vector space, or some combination of all four) that perfectly represents the behavior of a computer's CPU, ALU, or the whole machine.

Thanks for these amazing lectures! I have just one question - Can't we evaluate equations for next state and then implement them through Flip Flops. Like can't we write QA+ in terms of QA, QB and x, solve them through k-map, do the same for QB+ and then implement the circuit?

@ritwikdurga3855
@ritwikdurga3855 Жыл бұрын
@@nannubedi7773 Yes, you are correct. In digital circuit design, it is common to first write the Boolean equations for the next state of a flip-flop or sequential circuit and then implement the circuit using logic gates and flip-flops. One approach to implementing a sequential circuit is to write the Boolean equations for the next state of each flip-flop in terms of the current state of the flip-flops and the input signals. These equations can then be simplified using Boolean algebra or Karnaugh maps to obtain a minimized form. The minimized equations can be implemented using logic gates and flip-flops. For example, suppose we have a sequential circuit with two flip-flops, QA and QB, and an input signal x. We want to design a circuit that computes the next state of the flip-flops, QA+ and QB+, based on the current state and input signal. We can write the Boolean equations for the next state as: QA+ = f(QA, QB, x) QB+ = g(QA, QB, x) where f and g are Boolean functions. We can then simplify these equations using Karnaugh maps or Boolean algebra to obtain a minimized form. The minimized equations can be implemented using logic gates and flip-flops. So, to answer your question, yes, you can evaluate the equations for the next state and then implement them using flip-flops and logic gates. This approach is commonly used in digital circuit design.

I was wondering the same thing. I tried making y a function of x and the next states, and it ended with the correct result. However this leads me to ask. Since this is a Mealy machine, does the output change asynchronously? When I toggle the input values for it, the output changes irrespective of the clock. Is this behavior typical in mealy machines?
