Multiplexers

A multiplexor is an electronic device that allows multiple input signals to be combined into a single output signal, thus optimizing the use of transmission resources and reducing the need for multiple physical channels. This process, known as multiplexing, is essential in various applications such as data transmission, communications and industrial control systems.

Main functions of a multiplexer:

• Combination of signals: It integrates several input signals into a single output signal, facilitating its transmission through a single channel.
• Channel selection: It allows you to select which of the input signals is transmitted at a given time, through a controlled switching process.
• Resource optimization: Reduces the need for multiple physical channels, which lowers costs and complexity in the transmission infrastructure.

In summary, multiplexers are key components in communications and control engineering, as they allow the efficient transmission of multiple signals through a single channel, optimizing resources and reducing costs in various technological applications.
