WebJun 1, 2001 · However, in addition to the physical sources that are of interest, the measurement system, data acquisition and signal processing also introduce additional artificial incoherent noise sources. WebJun 4, 2016 · 1 When there are N coherent sound sources playing the same note at equal loudness, their sound waves add up to make a sine wave of the same frequency but most likely different amplitude (can be anything from zero to N times the amplitude of one wave), depending on their relative phase shifts.

WebIn addition, current wavefront correction routines seek only to reduce diffracted starlight. Here we present nonlinear estimation algorithms that include optimal estimation of sources incoherent with a star such as exoplanets and debris disks. AB - Direct imaging is in general necessary to characterize exoplanets and disks. WebApr 28, 2014 · The separation of incoherent sound sources has been of recurrent interest in the literature. A first possibility towards this objective is “supervised separation” which makes use of a set of available references on the sources of interest in order to separate their contributions at the measurement points. ...
