All signal multiplexing techniques were invented to permit a single physical communication channel to carry multiple different signals. This reduces the investment costs in physical communication channels: e.g. long distance telegraph lines, long distance telephone lines, microwave links, orbiting communication satellites, fiber optic cable.
Time Division Multiplexing can be implemented using either analog or digital signaling means.
Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
What is multiplexing and its diagram
error correction data compression
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.

In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
pulse shift technique
Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
What is multiplexing and its diagram
Multiplexing is the process of combining multiple signals over one media line. There are several types of multiplexing: frequency division, time division, and wavelength division.
Currently the mobiles use GSM(Geo Synchronous Mobiles ) and CDMA(Code Division Multiple Accesss) techniques. GSM inturn uses TDMA(Time Division Multiplexing) or FDMA(Frequency Division Multiplexing) or sometimes both to fit in the required criteria.
The T-1 channel combines 24x 64 Kbps channels into one single channel using Channel Bonding or Channel Aggregation.
Multiplexing techniques vary widely based on what is being multiplexed. Modern telecommunications use a very wide array of techniques including: TDM - examples: TDMA, T-carrier FDM - examples: DWDM Spatial - example: MIMO Code division - examples: CDMA Phase or polarization division - cable/satellite TV Statistcal - examples: packet mode (STS), FHSS etc etc. This is far from a complete list. I think the question needs to be more specific.
