Yes, it is an adverb, so it can answer the question "when" or more accurately "how frequently." The adverbs of frequency (daily, yearly, sometimes, occasionally) are sometimes listed as a separate classification from adverbs of time (suddenly, already, now, tonight, before, later).

In FSK the output frequency is dependent on the input bit stream. Here 2 (for Binary FSK) different carrier frequencies are used and they are switched according to input bit stream. When input is at logic1 output is freq. f1 and when input at logic0 output is freq. f2, where f1 and f2 are different.
Do you mean FDM or Frequency Division Multiplexing? If so, FDM is the division of a high frequency carrier into separate non-overlaping bands to be modulated by separate inputs. It's the modulation of several low frequency channels onto a high frequency carrier. Voice channels are low bandwidth inputs relative to the broadband carrier used to broadcast them.
If the light is a pure color, just one frequency, then there is nothing to separate.
