Analyzer system intended to visualize the sound signal in the time and frequency domain is presented. The system was realized in Matlab and it can process sound signals of wav files. Spectral analyzer takes into account the perception of the sound by humans and thus the magnitude spectrum can be visualized with frequency axis in Barks end ERBs. Spectrum can be weighted by the transfer function ...

We give necessary and sufficient conditions for a Banach space operator with the single valued extension property (SVEP) to satisfy Weyl’s theorem and a-Weyl’s theorem. We show that if T or T ∗ has SVEP and T is transaloid, then Weyl’s theorem holds for f(T ) for every f ∈ H(σ(T )). When T ∗ has SVEP, T is transaloid and T is a-isoloid, then a-Weyl’s theorem holds for f(T ) for every f ∈ H(σ(T ...
