Here’s a crude (but simple to implement) complex signal envelope detection scheme. By envelope detection, we mean estimating the instantaneous magnitude of a complex signal x c (n). Whether this ...

First- and second-order contrast stimuli can be described for the visual, auditory and tactile senses. Similarly, electrosensory contrast patterns vary over large spatial and temporal scales. Fast ...

October 3, 2013. Rohde & Schwarz has enhanced its new R&S SMW200A high-end vector signal generator by adding the R&S SMW K540 option for envelope tracking. This option enables quick and easy testing ...

Patrick Flandrin president of the association GRETSI. The notion of “signal processing” might seem like something impenetrably complex, even to scientists. However, the fact is that most of them have ...

Cerence has patented methods and systems for deessing speech signals, involving analyzing spectral envelopes to identify frequency content for deessing and applying deesser weights to sibilant sounds.
