Which of the following best defines a multiplexing technique?

The best definition of a multiplexing technique is the process of combining multiple signals onto one line. This technique is crucial in telecommunications and data transmission because it allows for the efficient use of bandwidth by enabling different signals to share the same communication medium. By multiplexing, a network can transmit various types of data simultaneously over a single channel without interference.

Multiplexing can take various forms, such as Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), and Code Division Multiplexing (CDM), each leveraging different approaches to ensure that multiple signals can coexist without degrading the quality of the transmission. In essence, this process maximizes the capacity of a communication channel, making it a fundamental concept in networking and data transmission technology.
