This paper presents technical foundations for a new technique of near-infrared transillumination-backscattering sounding, which is designed to enable noninvasive detection and monitoring of changes in the width of the subarachnoid space (SAS) and magnitude of cerebrovascular pulsation in humans. The key novelty of the technique is elimination of influence(More)
The aim of this paper is to demonstrate the ability of the proposed time domain and frequency domain instantaneous frequency (IF) estimators to track with high accuracy the very dynamically varying IF of a discrete-time signal. Our experiments with the analysis of small birds songs show that both these estimators enable to follow the IF which extends beyond(More)
