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.
An Electronic Device
it is an DAC (Digital to analogue converter
In in- bandsignalling , the control and management signals travles along with the data signals where as in out of band signalling the data and control signals travels in different channels
They are pheromones.
pheromones
They are chemical signals that insects release to convey information such as the location of food, or a signal to protect the hive and queen.

males use a protein to detect pheromones sent by females
Possible some types of pheromones.
That's pheromones. They happen without you noticing. You can't control them. They are silent, invisible, odourless signals.
