To supply the missing imaginary part to a real signal.
Call me a narrow thinking technician, but I still have no idea what "supply the missing part" is. Why do you miss it? Is it supposed to be there? I mean: that's the real signal. No imaginary part there. And now: you want to add an imaginary part to that. OK, so far. What model do you have? What are your expectations doing that? What are the properties of the signal you want to change? ....
