In the context of a sinusoidal representation for speech waveforms [1-4], it is shown that the excitation sine-wave phases can be modelled as a linear function of frequency, the slope being determined by the onset time of the underlying ... RJ Mcaulay,TF Quatieri - Advances in Speech Si...
This chapter describes spectral peak selection used in estimating the true spectrum of the target sequence, which is assumed to be composed of sinusoidal sequences. A compound sinusoidal sequence can be identified by repeating spectral peak selection fro
A sinusoidal model for the speech waveform is used to develop a new analysis/synthesis technique that is characterized by the amplitudes, frequencies, and phases of the component sine waves. These parameters are estimated from the short time Fournier transform using...
Time-domain representation of a sinusoidal FM signal (Eq. 1.1.3). 2. The linear-FM signal whose frequency satisfies Eq. (1.1.2) may be written (1.1.4)s2(t)=Arectt−t0−T/2Tcos2πf0(t−t0)+α2(t−t0)2+ψ,where, again, A is the amplitude and ψ a phase offset. The...
Of course many of the inputs to linear systems we would like to analyze are not sinusoidal. In this case, it is desirable to represent more arbitrary signal waveforms as a sum of sinusoidal frequency components. We then analyze each component individually and apply the concept of superposition ...
Principles and No Load Characteristics of Bearingless Motors with a Cylindrical Rotor In this paper, bearingless motors with a non-salient pole rotor are analyzed. Inductance functions are derived assuming MMFs are sinusoidal. Both the rotor and stator surfaces are also assumed to be smooth. Mutual...
A method based on the harmonicsinusoidal speech representation comprising of different amplitude and phase parameterization is proposed in Chazan et al. (2005). Another popular low footprint USS system, Flite, stores LP coefficients and residual error forevery speech frame of all the utterances in ...
(b) areas, EC2 (c), EC3 (d), and EC5 (e). Sinusoidal grey lines, idealised theta oscillations recorded from EC3. The size of each circle represents the strength of theta locking (mean resultant length,R) of each neuron. Watson U2test, *P < 0.05, **P < 0.01, ***P <...
The (dis)similarity of the waveforms that can not be accounted for by ITDs or ILDs, which can be parameterized by the maximum interaural cross-correlation IC (for example, the value of the cross-correlation at the position of the maximum peak). ...
The first one deals with the design of robust waveforms for sensing of turbulent phenomena. The second stage consists of sparsely representing the decomposition of the turbulence's impulse response, based on a physically driven decomposition basis. The tests conducted in a reduced scale experimental ...
