Truth Table
Truth table is a representation of a logical expression in tabular format. It is mostly used in mathematics and computer science.
The representation is done using two valued logic - 0 or 1. You can also refer to these as True (1) or False (0). It is used to see the output value generated from various combinations of input values.
Logic Gate Symbols
These input values are various variables & symbols ( commonly termed as LOGIC GATES). Below are the GATES and symbols- AND (symbolically: &)
- OR (symbolically: +)
- NOT (symbolically: !)
- NOR (Representing: Not – OR)
- NAND (Representing: Not - AND)
Truth Table Examples
In every truth table, each statement is typically represented by a binary digit or a variable. For better understanding, take a look at below examples.OR Gate Truth Table
