 Ultimately every process in a computer is the product of a digital [circuit](/Electronics/Circuits.md) that is working on binary values. In contrast to electrical circuits, digital circuits are not represented in an [analogue](/Hardware/Analogue_and_digital.md) fashion.
 
-Analogue circuits work on the basis of real continuous phenomena in the world: charges and currents. As a result, the key properties of a circuit - voltage, current and resistance - can vary over a wide range of values. This is the reason that we require) components like batteries and resistors: to control the natural flow of current and ensure that it only runs within desired parameters.

 In a standard electrical circuit, voltage, current and resistance can vary over a wide range of values however in the binary context we want to deal with discrete values (zeros and ones) which can be fed into the various [logic gates](/Hardware/Logic_Gates/Logic_gates.md).

-# Logic circuits
-
- > Now that we are familiar with the individual [logic gates](Logic_gates.md) and their truth conditions we are in a position to create **logic circuits**. These are combinations of logic gates controlled by inputs that can provide a range of useful outputs. The output of a logic gate is a function of the truth-values of the individual gates and their connections to each other.
-
-## Basic example
-
-In the below circuit we have the following gates connected to two inputs with one output, moving through the following stages:
-
-1. `AND`, `NOT`, `NOT`
-1. `AND`, `NOR`
-
-This is equivalent to the following truth table:
-
-````
-A    B   Output
-_    _   _____
-
-0    0     0       (1)
-1    0     1       (2)
-0    1     1       (3)
-1    1     0       (4)
-````

-
-## Applied example
-
-With this circuit we have a more interesting applied example.
-
-It corresponds to an automatic sliding door and has the following states
-
-* a proximity sensor that opens the doors when someone approached from outside
-* a proximity sensor that opens the doors when someone approaches from the inside
-* a manual override that locks both approaches (inside and out) meaning no one can enter of leave
-
-Here's a visual representation:
-
-![logic_circuits_5.gif](../img/../../img/logic_circuits_5.gif)
-
-The following truth table represents this behaviour, with A and B as the door states, C as the override and X as the door action (0 = open, 1 = closed)

-````
-A  B  C  X

-0  0  1  0
-1  0  1  1
-0  1  1  1
