Hearing the term logic gate certainly refers to things that are technical or rather the field of electronics. Of the many components used in the work of logic, component this one is the most widely discussed.
Even at other vocational schools such as Electricity or Information also touches a little about this logic gate. Arguably the logic gate is the basis of electronics and it must be known by the wider community, at least in the way it works.
In this article the author will review further about the understanding of logic gates, the types of logic gates and truth tables to facilitate understand the working principle of this one component. Immediately, a full review can be listened below:
Definition of Logic Gate
Logic gate or English terminology is Logic Gates is a basic component in the formation of digital electronic systems that function to convert one or several inputs into an output signal (output) and is Logic. As the name implies, this component is the place of entry and exclusion into logic.
Logic gates operate using binary numbers and use Boolean Algebra theory. Binary numbers are numbers that only have 1 and 0 as the symbol code. The use of Simbo 1 and 0 can also be interpreted as other logic such as High (high) and Low (low), True (true) and False (false), and On (on) and Off (off). This is adapted to the logic gate users.
Logic gates are also widely applied to electronic components such as Relay, Integrated Circuit (IC) Diodes, Transistors, as well as mechanical elements and many more. Because of their complex functions, it is not surprising that many components involve logic gates in their respective ways of working.
Types of Logic Gates + Truth Tables
In logic gates are divided into 7 basic types and are distinguished by the number of inputs (inputs) ) as well as the logic that is run. To make it easier we also give examples of Truth Tables in each type.
This Truth Table is a table that provides a description or possible logic that is issued based on the value of the input (input). Immediately, a full explanation can be listened below:
1. The AND Gate
The first is the AND gate. This AND gate requires 2 or more inputs and only 1 output appears. Output value 1 will be obtained if all input values are 1 while output value 0 will be obtained all or one of the input values is 0. To symbolize the AND gate operation, the dot symbol (".") Is used or does not use any symbol at all. 
|The Truth Table AND|
|X||Y||0  0||0||0|
|0||1||] 0  0 ] 1||0||0|
2. OR gate
Similar to AND, OR gate also requires 2 or more inputs and produces only 1 output. At the OR gate the output value will be 1 if one or all of the inputs are 1 and if you want to produce output 0 then the input value must be all 0. Sign that symbolizes OR gate operation is a plus ("+").
