Introduction
When we apply a input to a NOT gate it inverts the input.
Pre-Requisites:
Introduction about digital signals, Basic functions of logic gates
Activity:
In your physics just form a NOT gate with the help of teacher and find the output of the gate.
Real Life Question:
“Which logic gate is known as inverter?” “What is the commonly used symbol for NOT gate?”
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Inverter | A device or logic which produces the output opposite to the input. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|
Real life uses :
Many devices such as, Radio, Transistor, television, amplifiers, computers, watches etc.
Places to visit :
Your physics lab, where you can see the diagram representation of the NOT gate.
Practical examples around us
| Examples | Explainations |
|---|---|
| All the electronic devices | NOT gate is used in many electronic devices as the basic unit of the construction. |
What you learn in Theory:
This is the most basic gate, with one input and one output. It produces a ‘1’ output if the input is ‘0’ and vice-versa.
What you learn in Practice:
Electronic devices in daily practice use the digital system of signals i.e. they have only two inputs ON or OFF.
