Three multiplexing techniques is used to combine analog signals?
WDM and FDM
What is analog multiplexing?
Analog Multiplexer - Two analog signals as the input, one analog signal as the output, output is the product of the two inputs.
Which multiplexing technique transmits digital signal?
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
Why FDM is for analog signals and TDM is for digital signals?
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.
What type of multiplexing does cable tv use?
Does Cable television use time-division multiplexing
What Technology is used to modify analog signals to make them suitable for carrying data over a communication path?
Normally analog signals don't need any modifying, communications channels are naturally analog in nature. To multiplex several analog signals on one path one often uses FDM (Frequency Division Multiplexing), which requires modulating a carrier with each analog signal to be sent and then combining the modulated carriers. But I don't know if that was what you were referring to.
what are the Applications of time division multiplexing?
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.
How are analog signals received?
Analog signals can be received using an analog receiver.

How are analog signals transmitted-?
Analog signals are transmitted as electrical waves.
What converts a binary signal to analog?
an encoder is used to convert the binary signals into analog signals. the binary signals are fed to encoder section. then these signals are get converted into its equivalent analog signals. Binary DAC.
The device that combines the parallel input data into single serial output data is known as?
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.
