Dyadic discrete wavelet transform (DWT) has been used successfully in processing signals having non-oscillatory transient behaviour. However, due to the low Q-factor property of their wavelet atoms, the dyadic DWT is less effective in processing oscillatory signals such as embolic signals (ESs). ESs are extracted from quadrature Doppler signals, which are the output of Doppler ultrasound systems....
Neuronal spike detection is an essential pre-processing step for the analysis of extracellular brain signals in neuroscience. In resonance based signal decomposition, analyzed signal can be expressed as the sum of a ‘high-resonance’ and ‘low-resonance component’. A high-resonance component can be thought as a signal consisting of sustained oscillations and a low-resonance component can be thought...
