Understanding Not Gate Truth Table And Circuit Diagram

A Not Gate is an important basic digital logic gate used in digital electronics. It is a type of digital circuit where the output signal is different than the input signal. The output of a Not Gate is the inverse of the input signal, meaning that when the input is 0, the output is 1. The purpose of this gate is to invert the state of a signal before it goes to another circuit. In this article, we'll discuss the truth table and circuit diagram for a Not Gate and how it can be used to construct a digital logic system.

Overview of Not Gate

A Not Gate or “inverter” is a single-input, single-output digital logic gate. It outputs the opposite of its input signal; if the input signal is 0, the output signal is 1, and if the input signal is 1, the output signal is 0. Not Gates are one of the most fundamental gates used in digital electronics, and they are often used to invert signals before they go through other logic gates, like AND and OR gates.

Not Gate Truth Table

The truth table for a Not Gate is a very simple one. It only has two possible inputs and outputs. The first row of the table shows what happens when the input signal is 0, and the second row shows what happens if the input signal is 1. Here, you can see that when the input signal is 0, the output signal is 1, and when the input signal is 1, the output signal is 0.

Input	Output
0	1
1	0

Not Gate Circuit Diagram

A Not Gate circuit diagram consists of an input terminal, designated as IN, and an output terminal, designated as OUT. The input terminal receives a signal from an external source and passes it to the output terminal. The output terminal then either gives an output of 0 or 1, depending on the input. A Not Gate circuit uses a transistor to switch between the two states.

The circuit diagram of a Not Gate looks like this:

Here, the transistor acts as a switch, and it is activated when the voltage on the input terminal is high. When this happens, the transistor allows current to flow from the positive terminal to the negative terminal, thus outputting a 0. When the input voltage is low, the transistor does not allow current to flow, thus outputting a 1.

Conclusion

In conclusion, a Not Gate is an important electronic component used in digital systems. It is a single-input, single-output logic gate that inverts the input signal before passing it to the output. The truth table and circuit diagram for a Not Gate are also easy to understand. With its help, you can easily construct a digital logic system.
