A multiplexer is undoubtedly a very important switching system that has many inputs and one output. In this case, the input is the control input. Thanks to it, another input is selected, the signal of which is to go to the output of the system. It is worth learning more about it.

When is a multiplexer used?
Properly selected electrical equipment guarantees not only great functionality, but also safety. Therefore, it is required and its use is necessary. After all, it protects users from electric shock. The multiplexer certainly plays an important role here. It is important to know that it is used to select one of several available input signals and then transfer them to the output.
It should be remembered that the simplest multiplexer is a system with one control input. It is also necessary to know that the use of multiplexers is necessary in a situation where we want to use a much larger number of inputs than are available in the selected microcontroller. Such systems can be built directly into their structure. In addition, multiplexers are found in applications where a really large number of light-emitting diodes are used, and even in line follower robots.
This is precisely why they can handle a great many sensors. This device therefore acts as a switch and allows selective transmission of one of the many input signals. The multiplexer can have two selector inputs and in this case, depending on the setting, there will be an appropriate signal, which will then be sent to the output.
Basic types of multiplexers
As you know, multiplexers play very important functions. It is worth remembering that there are really technologically advanced models available.
Types of multiplexers:
- fiber optic multiplexer - is used in fiber optic technology to combine many optical signals, where there is one output signal. Such a multiplexer is used in modern telecommunications networks, where data transmission takes place using light. Its advantage is that it allows the transmission of large amounts of data over long distances.
-
digital multiplexer - has many functions and a wide range of applications. You need to know that it accepts many input signals. It is a multi-path communication node. One of the most popular digital multiplexers is the 4-bit one, which means that it sends 4 input signals to one output. There is also an 8-bit multiplexer, which means that it supports 8 input signals. - network multiplexer - a device that has the ability to transmit many signals on one channel. Network multiplexers are very popular because they allow sharing one communication channel or output, which significantly reduces costs. At the same time, they can be used for data compression and data encryption. Their use is therefore really wide and necessary when combining signals and in communication.
- electrical multiplexers - these are nothing more than controlled multiplexers that offer advanced features, meaning they allow high-speed connection while also allowing digital control. They can be used in parallel, but also in series.
- LAN multiplexers allow you to connect LAN networks. All you need to do is use one cable and connect it to a connector. They can have optical connections and a four-port switch.
- binary multiplexers - operate on binary data. They can be used in simple logic systems, such as microcontrollers. They are also necessary when switching between two states.
Applications of multiplexers in practice
Installation cables are largely responsible for the safety of users, but also the durability of the entire installation, so they are necessary. It is important to remember how important a role is played by modular equipment , such as a surge arrester for systems or photovoltaics. The operation of a multiplexer is very simple. It has a switching system and special control inputs. Indeed, multiplexers have a wide range of applications. Each of them allows the use of a much larger number of inputs than the one available in the selected microcontroller.
Note also that by choosing a fiber optic model of the power supply multiplexer, you can transmit a large amount of data with minimal signal losses. In turn, time-based ones are used in telecommunications, where optimizing network throughput is very important. Using a multiplexer also allows you to perform logical operations quickly and efficiently. During the power supply of the analog multiplexer, signals from different sources are switched in audio systems. This brings many benefits.
