Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
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.
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.
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.

In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)

In modern photography techniques, pictures are developed using digital technology. Light is captured by a digital sensor in the camera, which then converts the light into electronic signals. These signals are processed by the camera's software to create a digital image file, which can be viewed and edited on a computer or printed out as a physical photograph.
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.
This process is called multiplexing. Multiplexing allows multiple signals to be combined into a single transmission medium in order to optimize bandwidth usage and facilitate efficient communication.
Multiplexer(Multiplexing).In telecommunications and computer networks,multiplexing(also known as muxing) is a method by which multiple analog message signals or digital data streams are combined into one signal over a shared medium.
