What is the primary purpose of multiplexing?
To reduce the cost of transmission media
To enhance the security of data transmission
To increase the number of devices connected to a network
To allow several transmission sources to share a larger transmission bandwidth
Which of the following is NOT a basic multiplexing technique?
Time Division Multiplexing
Frequency Division Multiplexing
Wavelength Division Multiplexing
Signal Division Multiplexing
What does FDM stand for?
Frequency Digital Modulation
Frequency Data Management
Frequency Division Multiplexing
Frequency Division Modulation
In Frequency Division Multiplexing, how are signals separated?
By using different cables
By using digital signals
By using guard bands
By using time slots
What is the main advantage of Wavelength Division Multiplexing (WDM)?
It requires less bandwidth
It uses the high-data-rate capability of fiber-optic cable
It is easier to implement than TDM
It is cheaper than FDM
What is a main property of Synchronous TDM?
It is used only for analog signals
It allows for maximum utilization of the link
Each device is assigned a fixed time slot
Time slots are allocated based on demand
What is the role of a demultiplexer (DEMUX) in a multiplexed system?
To combine multiple signals into one
To separate a composite signal back into its original components
To modulate signals onto different carriers
To allocate bandwidth to different channels
In Asynchronous TDM, how are time slots allocated?
They are fixed for all devices
They are preassigned to each device
They are allocated dynamically based on demand
They are based on the frequency of signals
What is the minimum bandwidth required for four channels of 100 kHz each with a 10 kHz guard band?
430 kHz
440 kHz
400 kHz
500 kHz
Which multiplexing technique is used for digital signals?
Frequency Division Multiplexing
Wavelength Division Multiplexing
Time Division Multiplexing
Analog Division Multiplexing
