Equivalent Gates
Now we will see how we can form not gate using universal gates(NAND and NOR gate).
NOT Gate Using NAND Gate
In digital electronics, we can implement the NOT gate logic by using the NAND gates only. For this, we tie all inputs of the NAND gate together and apply the input signal to the common input line as shown in the following figure.
The logical expression for this circuit is given by,
[Tex]Y = \overline{A} [/Tex]
NOT Gate Using NOR Gate
The NOR gate is another logic gate that can be used to implement the NOT gate logic. To realize the NOT gate circuit using NOR gate, we join all input lines of the NOR gate together and then apply the input signal to this common input line.
The operation of this circuit can be described using this equation,
[Tex]Y = \overline{A + A} = \overline{A} [/Tex]
NOT Gate
This article will explain the concept of NOT gate operation in digital electronics along with its truth table, logic symbol, switching circuit diagram, etc. The NOT gate is one of the main building blocks of Digital Logic Circuits. A NOT Gate, also called an inverter, has only one input and one output. It is a logic gate whose output is always the complement of its input.
Here, we will cover NOT Gate using transistors with the working of the circuit and its applications, advantages, and disadvantages, accompanied by solved examples and answers to frequently asked questions.
