In this paper we point out new properties, composition, wideband filtering and quadratic principle, of the cross-PsiB-energy operator which measures the interaction between two non- stationary signals. These properties are useful for some signal processing applications. We show that due to its bilinearity, PsiB satisfies the quadratic superposition principle that can be used efficiently for transient...
In this paper, a signal-filtering method based on empirical mode decomposition is proposed. The filtering method is a fully data-driven approach. A noisy signal is adaptively decomposed into intrinsic oscillatory components called intrinsic mode functions (IMFs) by means of an algorithm referred to as a sifting process. The basic principle of the method is to make use of partial reconstructions of...
