On the use of short-time fourier transform and synchrosqueezing-based demodulation for the retrieval of the modes of multicomponent signals
(Elsevier Science, 2021-01)
In this paper, our goal is to compare different recent time-frequency (TF) approaches to retrieve the modes of multicomponent signals (MCSs). While it is acknowledged that the synchrosqueezing transform (SST) improves the ...
Voice Jitter Estimation Using High-Order Synchrosqueezing Operators
(Institute of Electrical and Electronics Engineers, 2020-12)
Voice jitter is defined as a random perturbation of the glottal cycle duration which can be useful for voice parametrization and that usually depends on finding fiducial points in this signal. In this paper, a novel ...
Amplitude and phase retrieval in simultaneous pi/2 phase-shifting heterodyne interferometry using the synchrosqueezing transform
(Optical Society of America, 2015-03)
This paper presents a method for amplitude and phase retrieval in simultaneous π/2 phase-shifting heterodyne interferometry. The used optical setup admits the introduction of a temporal carrier and simultaneously verifies ...
Deep Recurrent Learning for Heart Sounds Segmentation based on Instantaneous Frequency FeaturesAprendizaje profundo y recurrente para la segmentación de sonidos cardíacos basado en características de frecuencia instantánea
(Universidad de Buenos Aires. Facultad de Ingeniería. Departamento de Electrónica, 2020-10)
In this work, a novel stack of well-known technologies is presented to determine an automatic method to segment the heart sounds in a phonocardiogram (PCG). We will show a deep recurrent neural network (DRNN) capable of ...
