What is a NOT gate (inverter) and its function.

1 Answer

A NOT gate, also known as an inverter, is a fundamental digital logic gate in electronics. Its primary function is to invert the input signal, meaning that it takes an input value of either 0 or 1 (binary) and produces an output that is the opposite of the input. In other words, if the input is 0, the output is 1, and if the input is 1, the output is 0.

The symbol for a NOT gate is usually represented as a triangle with a small circle at its input, indicating the inversion operation. The input signal is connected to the flat side of the triangle, and the output signal is taken from the pointed side.

Here's a truth table that shows the relationship between the input and output of a NOT gate:

Input    Output
0    1
1    0

The NOT gate is a fundamental building block in digital circuits and plays a crucial role in various logic operations, such as complementing signals, creating logic functions, and designing more complex logic gates and circuits. It's used in combination with other logic gates to create more complex logical functions and to design circuits that perform arithmetic, memory storage, and decision-making tasks in computers and digital systems.
