Question

Which of these multiplexing techniques is digital for combining several low -rate channels into one high-rate one

Answer 1

Answer:

The 3 types of multiplexing techniques include the following.

1. Frequency Division Multiplexing (FDM)
2. Wavelength Division Multiplexing (WDM)
3. Time Division Multiplexing (TDM)

in telecommunications and computer networks, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The multiplexed signal is transmitted over a communication channel such as a cable.

Answer 2

Answer: The 3 types of multiplexing techniques include the following.

1.Frequency Division Multiplexing (FDM)

2.Wavelength Division Multiplexing (WDM)

3.Time Division Multiplexing (TDM)

Explanation:

Step :1 Multiplexing, often known as muxing, is a technique used in computer networking and telecommunications to combine several analogue or digital signals into a single signal via a common media. The goal is to share a physical transmission medium, which is a limited resource.

Both TDM and FDM are multiplexing methods. TDM is effective with both analogue and digital signals, whereas FDM is designed for analogue signals. TDM is primarily utilised in digital communications, though. Synchronization pulse is crucial in TDM, but Guard Band is necessary in FDM.

Step :2 In addition to being widely employed in 3G mobile cellular networks—4G and 5G largely use OFDM—CDM is also commonly used in digital television and radio broadcasts. Code-division multiple access, or CDM, is a method that allows numerous signals from various sources to be supported simultaneously.
