Review on multiplexers

Multiplexor – a device that has several signal inputs, one output, one or more control inputs. The equipment transmits a signal from one of the inputs to the output. In this case, the selection of the required input is made by choosing a combination of control signals.


Multiplexers can be used in frequency dividers, flip-flops and shifters, etc. They are also used to convert parallel binary code into serial.

In practice, devices are most often used in telecommunications, video surveillance, recording. The use of a multiplexer in communication networks reduces the network maintenance cost.

With such equipment, the organization of the transmission of one hundred / two hundred conversational signals occurs without laying a telephone cable. A single channel or more device copes well with the tasks. And the savings are significant.

Also, multiplexers are effective in organizing video conferencing. Two-way data transmission, processing, displaying real-time data at a distance are part of the functions that the switch performs.

Technical Center “ZAiS” sells multiplexers, data acquisition and switching systems from leading manufacturers. We would like to partially acquaint you with the offered assortment.
