WebIn mathematics and signal processing, an analytic signal is a complex-valued function that has no negative frequency components. The real and imaginary parts of an analytic signal are real-valued functions related to each other by the Hilbert transform.. The analytic representation of a real-valued function is an analytic signal, comprising the original … WebOne can probably also write these as one equation with the absolute value function. In any case, the point is the Hilbert transform seems to contain a discontinuity, which is what makes this particularly confusing to calculate I suspect. I know it is somewhat "handwaivy", but I think the general idea/result is correct, so hope this helps!
