Question

Make a logic symbol and write a Boolean expression for NOT gate.

Answer 1

Logic gates are digital gates and that they perform a given function which is predetermined but depends upon the input given. Also, they're fed digital inputs-0&1. These are the building blocks of integrated circuits. Gates have only two inputs- 0 & 1.

Complete step by step answer:
NOT gate is an electronic circuit that produces an inverted version of the input that we get as the output. It's one input A and one output Y as shown within the figure below;

The truth table for a NOT gate can be written as

A	Y
1	0
0	1

Additional information:
NOT gate is also known as Inverter because it inverts the given input. For example, if the input is 1 then the output is 0 and vice versa. Also, it is well established that it inverts the input so. A standard Inverter which we call the NOT Gate, is usually made up from transistor switching circuits that do not switch from one state to the next instantly, there will always be some delay in the switching action. NOT gate can be used in combination with OR gate to get NOR gate.

Note: The (o) present at the end of the NOT gate symbol denotes a signal inversion of the output signal. NOT gates can also be made from NAND and NOR gates by connecting them together, all their inputs to a common input signal for example. Each NOT gate has only one input signal.
