What is the purpose of multiplexing in digital circuits?

Multiplexing is a technique utilized in digital circuits to allow multiple signals to simultaneously share a single communication channel or medium. This process is essential in efficiently using available resources, enabling the transmission of data from various sources over a common line, which helps in optimizing bandwidth and reducing the amount of wiring needed.

By using multiplexing, different signals can be discerned based on their assigned time slots or frequencies, allowing them to coexist without interfering with each other. This is particularly advantageous in applications such as telecommunications and data communication systems, where multiple data streams need to be sent concurrently. The effectiveness of multiplexing in combining different signals into one transmission path illustrates its crucial role in modern digital communication systems.
