How is multiplexing done?

Multiplexing is a method used by networks to consolidate multiple signals -- digital or analog -- into a single composite signal that is transported over a common medium, such as a fiber optic cable or radio wave.

How is multiplexing possible in modulation?

Multiplexing is a process to send one or more signals over the same communication channel. The modulation process (Amplitude Modulation or Angle Modulation) is an example of multiplexing as both the message signal and the carrier signal are transmitted on the single communication channel.

What is FM multiplex?

To transmit stereo music, FM is enhanced by stereo multiplexing which carries both L and R audio channel content. With the digital age, Radio Data System (RDS) enables FM to carry text information such as traffic, weather, and radio station information which can be displayed on the end-user's device interface.

How does T 1 multiplexing work?

A T-1 multiplexer has 24 ports (one for each time slot). Therefore, time slot one = port one; time slot two = port two; etc. In a TDM transmission, each time slot is always present even if only one time slot actually has data. The bandwidth is always used.
