Question: 1 / 400

What is the function of a multiplex system in radio communication?

Allows one-way communication only

Permits simultaneous transmission of multiple signals

The function of a multiplex system in radio communication is to permit simultaneous transmission of multiple signals. This capability is essential for efficient use of the available bandwidth, allowing various channels or data streams to share the same communication medium without interference. In practical terms, this means that several conversations or data transmissions can occur at the same time on the same frequency, which greatly enhances the overall efficiency and capacity of the communication system.

This capability is particularly valuable in situations such as emergency services, where multiple teams may need to communicate concurrently, ensuring that critical information can be relayed without delay. Hence, using multiplexing increases the functionality of communication systems and supports a more organized flow of information.
