About a Partial Differential Equation-Based Interpolator for Signal Envelope Computing: Existence Results and Applications
Figure 4
Envelope calculus by (17) with . In (a), at this stage, the two envelopes overlap by location. In (b), less overlap and practically the asymptotic solution are almost reached. In (c), the stability of the evolution leading to the solution.
