Webinar on Chromatic Derivatives and Applications
April 26 @ 9:30 am - 10:45 am MMT
Chromatic derivatives are special, numerically robust differential operators which preserve spectral features of a signal; the associated chromatic expansions, when truncated, provide approximations which accurately capture local features of a signal. For this reason they allow digital processing of continuous time signals often superior to processing of discrete samples of such signals. We present the motivation for introducing these notions, their main properties and mention some of their applications.
