In this video, what is Finite State Machine (FSM), what is Mealy Machine, and Moore Machine is explained. And at the later part of the video, the State Transition Diagram, which is a graphical way to visualize the behavior of the FSM is also explained.
What is Finite State Machine?
A finite State machine is an abstract model to represent Sequential Circuits.
The FSM has a finite number of states. And based on the inputs it receives and the current state of the machine, it makes a transition from one state to another state.
All the sequential circuits are essentially Finite State Machines.
Mealy Machine and Moore Machine :
In the Finite State Machines, depending on how to output is generated, there are two FSM models.
1) Mealy Machine
2) Moore Machine
The behaviour of the Finite State Machine can be represented in three different ways:
1) State Transition Diagram
2) State Table
3) State Equation
In this video, the state transition diagrams of the Mealy and Moore machine are explained.

![Half Subtractor and Full Subtractor Explained
In this video, the Half Subtractor and Full Subtractor are explained in detail.
By watching this video, you will learn what is half and full subtractors and how to implement a full subtractor using half subtractors.
Timestamps:
0:00 Half Subtractor
3:34 Full Subtractor
11:11 Full Subtractor using Half Subtractors
What is Half Subtractor?
It is the combinational circuit that performs the subtraction of two input bits and generates the difference and borrow bits as an output.
The logic circuit of the Half subtractor consists of one two-input XOR gate (Difference output) and, one AND gate and NOT gate (Borrow Output).
The Boolean expression of Difference and Borrow output of Half Subtractor:
D = A (XOR) B (The difference output)
B = AB. (The borrow output)
The half-subtractor circuit can perform the subtraction of two one-bit numbers without any borrow input. It is suitable for the subtraction of the two one-bit numbers at the LSB positions.
Full Subtractor:
The Full-subtractor is the combinational circuit that performs the subtraction of two input bits and the incoming borrow bit and generates the difference and the borrow bits as an output.
The Boolean expression of Difference and Borrow output of Full Subtractor:
D = A (XOR) B (XOR) Bin
Bout = AB + Bin [ A (XOR) B ]
The Full Subtractor circuit can be implemented using the two Half Subtractors and one OR gate. In this video, the design of Full Subtractors using Half Subtractors is also explained.
