The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
Modulation schemes depends on frequency.
It depends on where your home is.
depends on type of modulation and other variables
depends. what kind of dolphin?
it depends what you are talking about...
It depends on how thick the wall is.
That depends entirely on the species.
it depends on what time zone you are in
Depends which part of Mexico...
it depends on your religious beliefs
it depends on the meridians the difference between each meridian is 4 minutes so every 15 is equal to one hour
It can be anything at all, from yoctowatts to terawatts. You must state the power output at some modulation index before I can calculate it for some other modulation index. By the way . . . the answer also depends on the method of modulation, which you have not mentioned. For example, with pure FM, the transmitted power doesn't change, regardless of the mod-index.
