Polynomial interpolation to analytic functions can be very accurate, depending on the distribution of the interpolation nodes. However, in equispaced nodes and the like, besides being badly ...

Abstract: Diplexer synthesis is challenging due to the strong interaction between channels. Conventional synthesis techniques decompose a diplexer into two bandpass filters connected to a junction and ...

Abstract: Nonnegative matrix factorization (NMF) models are widely used to analyze linearly mixed nonnegative data. When the data is made of samplings of continuous signals, the factors in NMF can be ...
