Wavelet Estimation of THD Based on Hilbert Transform Extraction

چکیده
In evaluating the quality of waveform energy, Total Harmonic Distortion can be one of the unique testing parameters showing the disturbance effect on pure waveform or regenerated waveform. As harmonics may added to distort the fundamental waveform, the analysis of signal dynamic characteristic and the measurement of harmonics effect on the integrity of the waveform will be study to explore and enhance the testing process. In previous work, Fourier Transform and Wavelet Transform algorithms were employed to analyze characteristics of a waveform. In this work, Hilbert Transform in pairs with Wavelet Transform algorithms, that draw a lot of researchers attention, will be investigated as new propose testing technique to identify signal distortion with the effect on the waveform energy and fundamental frequency. This new proposed testing technique will be validated with conventional methods in terms of accuracy, number of collected data samples, and complexity of data compiling.

Optical phase extraction algorithm based on the continuous wavelet and the Hilbert transforms
In this paper we present an algorithm for optical phase evaluation based on the wavelet transform technique. The main advantage of this method is that it requires only one fringe pattern. This algorithm is based on the use of a sًecond /2 phase shifted fringe pattern where it is calculated via the Hilbert transform. To test its validity, the algorithm was used to demodulate a simulated fringe p...

متن کاملHyperspectral Image Analysis Using Hilbert-huang Transform
ABSTRACT: Hyperspectral images, which contain rich and fine spectral information, can improve land use/cover classification accuracy, while traditional statistics-based classifiers cannot be directly used on such images with limited training samples. The commonly used method to solve this problem is dimensionality reduction, and this can be done by feature extraction for hyperspectral images. T...
متن کاملA New Method for Multisensor Data Fusion Based on Wavelet Transform in a Chemical Plant
This paper presents a new multi-sensor data fusion method based on the combination of wavelet transform (WT) and extended Kalman filter (EKF). Input data are first filtered by a wavelet transform via Daubechies wavelet “db4” functions and the filtered data are then fused based on variance weights in terms of minimum mean square error. The fused data are finally treated by extended Kalman filter...
