CN14 Multiplexing

Which definitions best define multiplexing?

• combination of information from multiple sources over multiple media
• combination of information over multiple media
• combination of information from multiple sources over a shared medium
• combination of information

There are FOUR (4) basic approaches to multiplexing. Which of the following is NOT one of them?

• Transmission Division Multiplexing (TDM)
• Code Division Multiplexing (CDM)
• Frequency Division Multiplexing (FDM)
• Wavelength Division Multiplexing (WDM)

How can multiple radio stations transmit simultaneously with little interference?

• use separate carrier amplitudes
• use the same carrier frequencies
• use separate carrier phases
• use separate carrier frequencies

How does a demultiplexer distinguish between different frequencies?

• by turning the listener on and off
• by requesting transmitter to send one at a time
• by using a set of filters
• none of the options

Wavelength Division Multiplexing (WDM) refers to the application of Frequency Division Multiplexing (FDM) to ____.

• unshielded twisted pair
• optical fiber
• coaxial cable
• shielded twisted pair
