Digital
3 multiple choice options
Principle: Orthogonal subchannels
Differentiator: Orthogonal subchannels
OFDM
3 multiple choice options
Principle: Time slots
Differentiator: Time slots
TDM
3 multiple choice options
Principle: Different wavelengths of light
Differentiator: Different wavelengths
WDM
3 multiple choice options
Principle: Dense set of wavelengths
Differentiator: Higher density of wavelengths
DWDM
3 multiple choice options
Principle: Frequency bands
Differentiator: Frequency bands
FDM
3 multiple choice options
Principle: Variable time intervals
Differentiator: Dynamically allocated time slots
ATDM
3 multiple choice options
Principle: Fixed and synchronized time intervals
Differentiator: Fixed and synchronized time slots
STDM
3 multiple choice options
Principle: Unique codes for each channel
Differentiator: Unique codes for different channels
CDM
3 multiple choice options
Fixed time slots synchronized to a clock for each channel
STDM
3 multiple choice options
Transmits each signal from one input source via a single time slot through the creation of different slots
STDM
3 multiple choice options
Multiplexing that divides the allotted frequency into multiple channels (subcarriers) like frequency hopping and direct sequencing
**allows simultaneous transmission of data on each subchannel
OFDM
3 multiple choice options
Each user periodically gets the entire bandwidth for a small burst of time, i.e. entire channel is dedicated to one user but only for a short period of time
TDM
3 multiple choice options
Multiplexing used commonly in telecommunication systems and computer networks that use laser systems to send light signals over fiber optic cables
WDM
3 multiple choice options
Optical multiplexing using different light wavelengths for channels
WDM
3 multiple choice options
Transmission technique used with wireless devices that use the 5-GHz radio band and can achieve a data rate as high as 54 Mbps
OFDM
Employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code)
CDM
3 multiple choice options
A multiplexing technique used extensively by the military and cellular phone companies in which binary 1s and 0s are replaced with larger, unique binary sequences to allow multiple users to share a common set of frequencies
CDM
3 multiple choice options
Assigns a unique code to each channel, and all channels share the same frequency band simultaneously
CDM
3 multiple choice options
Randomly allocates time slots to different data signals depending on the rate at which they are being generated from the source
ATDM
3 multiple choice options
It is very extensively used in computer communication and telecommunication
TDM
3 multiple choice options
Used to send and receive digital signals between connected devices
TDM
3 multiple choice options
Multiplexing used for television network to broadcast local news content using analog signals
FDM
3 multiple choice options
Divides the available bandwidth into frequency bands, and each band is used for a different communication channel
FDM
3 multiple choice options
Divides time into fixed intervals, with each interval assigned to a different channel. Data from each channel is transmitted in its assigned time slot
TDM
3 multiple choice options
Multiplexes multiple signals onto different wavelengths of light in a fiber optic cable
WDM
3 multiple choice options
