Correlation transfer function analysis as a biomarker for Alzheimer brain plasticity using longitudinal resting-state fMRI data

Neural plasticity is the ability of the brain to alter itself functionally and structurally as a result of its experience. However, longitudinal changes in functional connectivity of the brain are ...

Modeling head- and pinna-related transfer functions using boundary elements and finite differences with volume penalization

Head-related transfer functions (HRTFs) describe the free-field sound transmission to the ears and are fundamental to most virtual and augmented reality systems. However, measuring HRTFs is ...

Transfer function analysis has a trigonometric booby trap

For some very simple circuit, a two-pole RC lowpass filter in this case, we can very easily derive the algebraic transfer function and look at the circuit’s gain and phase properties. An examination ...
