-'''Virtual signals''' can used as signals in [[Circuit network]]s. They can be outputted by all devices that can send signals to the circuit network. If a circuit network contains virtual signals, they act like a normal item signal, so you can perform comparisons and arithmetical operations.
-== Containing signals ==
-Currently Factorio has 20 virtual signals:
-* numbers 0-9
-* letters A-F
-* colored (blue, green, red, yellow)
-== Usage ==
-Virtual signals are useful to control [[Automatic control/Devices|devices]] if the control not depend on items (e.g. if you want to have the pollution as signal). They also are used as output by [[Arithmetic combinator]]s, where two amounts of items are processed and you can't decide which item is the output.
-== Logic signals ==
-[[File:logic_signals.png|300px|thumb]]
-There are also some logic signals in Factorio. They have special functions to control multiple-signal-informations. These three signals are:
-* everything (red)
-* anything (green)
-* each (yellow)
-=== Everything ===
-; As input

-|}
-: The "Everything" signal works like a logical AND. It can only be used as the left term of the circuit condition. The condition will only be true if the condition is true for all signals. Attention with the number 0. If there is a signal with amount 0, it will not considered as signal.
-: If the decider combinator output is set as "Input count" and not "Everything", all input signal amounts of the decider combinator are summed and outputted.

-|}
-: If "Everything" is set as output, all input signal items are outputted, either with amount 1 ("1") or with their input amount ("Input count").
-: It can only be set as output, if the left condition term is "Everything" or "Anything".
-=== Anything ===

-: It works similar than "Everything", but the condition is true if the condition for at least one input signal is true (logical OR).
-; As output
-: The "Anything" signal cannot be set as output.
-=== Each ===

-: The "Each" signal also performs the operation for all input signals, but the condition is not definitely true or false, but true or false for each input signal.
-: If the output is "1" and not "Each" (decider combinators only), the configured output will only be outputted if at least one condition is true. If the output is "Input count" and not "Each" (arithmetic combinator too), all amounts of input signals where the condition is true or all results of mathematical operations for each input signal are summed and outputted.

-|}
-: The "Each" signal can only be set as output if the left input signal is also "Each". A decider combinator outputs only the input signals whose condition is true. An arithmetic combinator ouputs the input signals with an amount that is the result of the operation.
