WebThe Hilbert transform of g(t) is the convolution of g(t) with the signal 1/πt. It is the response to g(t) of a linear time-invariant ﬁlter (called a Hilbert transformer) having impulse … WebThe Hilbert transform calculates the "analytic" signal, i.e. it calculates a matching imaginary part to a real signal by shifting the phase by 90 degrees in the frequency domain. It's reputation of calculating the "envelope" comes mainly from communication technology.

WebIn this paper, with the help of a Fenchel-Legendre transform, which is used in various problems involving symmetry, we generalized a number of Hilbert-type inequalities to a general time scale. Besides that, in order to obtain some new inequalities as special cases, we also extended our inequalities to discrete and continuous calculus.
