Probabilistic amplitude and frequency demodulation
A number of recent scientific and engineering problems require signals to be decomposed into a product of a slowly varying positive envelope and a quickly varying carrier whose instantaneous frequency also varies slowly over time. Although signal processing provides algorithms for so-called amplitudeand frequencydemodulation (AFD), there are well known problems with all of the existing methods....

t=1 exp (k1 cos(θt − θt−1) + k2 cos(θt − θt−2)) , (2) p(yt|at, θt) = Norm(yt; at cos(θt + ω̄t), σ 2 y). (3) The joint distribution over the amplitudes is a multivariate truncated Gaussian. Therefore, when the von Mises process becomes an independent, uniform distribution (k1 = 0 and k2 = 0), the model reduces to that of Sell and Slaney with a particular spectral weighting function determined by ...
متن کاملProbabilistic Amplitude Demodulation
Natural sounds are rich in long-range temporal structure – like the sentences and phonemes of speech – and a good model of such structures should help solve difficult problems in machine-audition. We propose a new representation for the long-range features in sounds in terms of a product modulatory processes, that form a cascade from slow to fast. In order to produce this representation we argu...
متن کاملAmplitude and Phase Analysis of EEG Signal by Complex Demodulation
Analysis of amplitude and phase characteristics for delta, theta, and alpha bands at localized time instant from EEG signals is important for the characterizing information processing in the brain. In this paper, complex demodulation method was used to analyze EEG (Electroencephalographic) signal, particularly for auditory evoked potential response signal, with sufficient time resolution and de...
