WebSome obvious properties of the Hilbert transform follow directly from the deﬁnition. Clearly the Hilbert transform of a time-domain signal g(t) is another time-domain signal ˆg(t). If g(t) is real-valued, then so is ˆg(t). Linearity: The Hilbert transform is linear, i.e., if a 1 and a 2 are arbitrary (complex) scalars, and g 1(t) and g
