1.	Time division multiplexing: Digital signal:: Frequency division multiplexing:?(a) Pulse code modulated signal(b) Continuous wave signals(c) Analog signal(d) Pulse position modulated signalThe question was asked during an online interview.This is a very interesting question from Frequency Division Multiplexing in section Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics
Answer» The correct choice is (c) Analog signal To explain I would say: The two most COMMON types of MULTIPLEXING are frequency-division multiplexing (FDM) and time-division multiplexing (TDM). Two variations of these basic METHODS are frequency-division multiple ACCESS (FDMA) and time-division multiple access (TDMA). In general, FDM systems are used for analog information and TDM systems are used for digital information.
