What does FDM stand for and what is its focus?
FDM stands for Frequency Division Multiplexing, focusing on analog and digital signals.
What does TDM stand for and what is its focus?
TDM stands for Time Division Multiplexing, focusing on digital signals.
What is STDM and how does it differ from TDM?
STDM stands for Statistical Time Division Multiplexing, which allocates time slots based on demand rather than fixed intervals like TDM.
What does CDM/CDMA stand for and what is its application?
CDM stands for Code Division Multiplexing, and CDMA stands for Code Division Multiple Access, both used for digital communication.
What does OFDM stand for and what is its primary use?
OFDM stands for Orthogonal Frequency Division Multiplexing, primarily used in digital broadcasting and broadband.
What do WDM, CWDM, and DWDM stand for?
WDM stands for Wavelength Division Multiplexing, CWDM stands for Coarse Wavelength Division Multiplexing, and DWDM stands for Dense Wavelength Division Multiplexing, all focusing on optical communication.
