WebApr 15, 2024 · Background Anesthesiologists are required to maintain an optimal depth of anesthesia during general anesthesia, and several electroencephalogram (EEG) processing methods have been developed and approved for clinical use to evaluate anesthesia depth. Recently, the Hilbert–Huang transform (HHT) was introduced to analyze nonlinear and … WebHilbert-Transformation. Die Hilbert-Transformation ist in der Funktionalanalysis, einem Teilgebiet der Mathematik, eine lineare Integraltransformation. Sie ist nach David Hilbert benannt, welcher sie Anfang des 20. Jahrhunderts bei Arbeiten am Riemann-Hilbert-Problem für holomorphe Funktionen formulierte.
