envelopedetected
Envelopedetected is a term used in signal processing to describe the act or result of extracting the envelope of a signal. The word blends envelope, the slowly varying amplitude of a carrier, with detected, indicating that the envelope has been isolated from the carrier. In practice, envelopedetected can refer to either the process of envelope detection or to data and features that have undergone such processing. The term functions as a conceptual label rather than a fixed technical standard.
Usage of the term is informal and relatively new; it appears in some algorithm descriptions, educational materials,
Common methods to obtain an envelope include analog approaches using diode detectors and RC filters, as well
Limitations include sensitivity to noise, distortion of rapid envelope changes, and loss of phase information. See
