Estimation of the Parameters of Sinusoidal Signal Components and of Associated Perceptual Musical Interpretation Effects
نویسندگان
چکیده
The estimation of the parameters of a sinusoidal signal is an old problem and has been extensively studied in the literature. We propose here to use a well known method ; the estimation of the parameters by using the Fast Fourier Transform (FFT) and by taking into account the mutual influence of a part of the frequential peaks. When we extract the sinusoidal part of the signal, we obtain a noise composed, in the best case, by the background noise and the instrumental noise. In this situation estimating the SNR can allow us to detect some interpretation effect.

Perceptual and Physical Aspects of Musical Sounds
This paper presents the research involved in the elaboration of the timbre model, a signal model which has been built to better understand the relationship between the perception of timbre and the musical sounds most commonly associated with timbre. The elaboration of the timbre model involves an overview of the related topics in many fields. In particular the signal processing, perceptual and ...
متن کاملDynamic Performance Analysis of High-Frequency Signal Injection Based Sensorless Methods for Interior Permanent Magnet Synchronous Motors
This paper focuses on three commonly used sensorless methods based on high-frequency signal injection; namely, the rotating sinusoidal injection in the stationary reference frame, the pulsating sinusoidal injection in the estimated synchronous reference frame, and the pulsating square wave injection in the estimated synchronous reference frame. Although these methods have found applications in ...
متن کاملEstimation of harmonic interference parameters of surface-NMR signal using an adaptive method and residual signal power
Surface nuclear magnetic resonance (surface-NMR) method is a well-known tool for determining the water-bearing layers and subsurface resistivity structure. Harmonic interference is an inevitable interference in surface-NMR measurements. Accurate estimation of harmonic interference parameters (i.e., fundamental frequency, phase and amplitude) leads to better retrieval of power-line harmonics and...
متن کاملWindowing Effects of Short Time Fourier Transform on Wideband Array Signal Processing Using Maximum Likelihood Estimation
During the last two decades, Maximum Likelihood estimation (ML) has been used to determine Direction Of Arrival (DOA) and signals propagated by the sources, using narrowband array signals. The algorithm fails in the case of wideband signals. As an attempt by the present study to overcome the problem, the array outputs are transformed into narrowband frequency bins, using short time Fourier tran...
