Two-wavelength interferometric signal processing by recurrence filtering method

SPIE Proceedings, 1999
Two-wavelength interferometry technique provides accurate measurement of geometric values in extended range of measurement definition. We propose the approach to two- wavelength interferometric signal processing based on recurrence data filtering. Interferometer is illuminated by monochromatic light source on two wavelength simultaneously. The position

An improved method for speech signal processing based on adaptive filter

2014 IEEE International Conference on Communiction Problem-solving, 2014
Based on the adaptive filtering mode, we discussed and analyzed how to improve the quality of microphone array speech enhancement and reduce the complexity of the algorithm. This paper described a new variable step least mean square (LMS) algorithm which could reduce the effect of input noise to step factor, improve the performance of the algorithm ...

A method for speech signal processing based on band filtering of the logarithmic spectrum

Automation and Remote Control, 2014
We propose a method for speech signal preprocessing based on band filtering of the logarithmic amplitude spectrum with a filter with odd impulse characteristic. With such filtering, we can detect local nonuniformities in the spectrum of a speech signal caused by abrupt inclinations of the vocal tract frequency characteristic, which represent useful ...

Application of Wavelet Filter Method in Optical Tweezers Signal Processing

Advanced Materials Research, 2013
One limitation on the performance of optical tweezers (abbreviated as OT) is the noise inherently present in each setup. Therefore, it is the desire to minimize and possibly eliminate the noise from the OT experiments. In this paper, a filter method based on wavelet analysis is proposed.

OCT Signal Processing Method Based on Sequential Kalman Filtering

Advanced Materials Research, 2015
Optical current transformer (OCT) measured current signal which is mixed with strong random noise. The measured readings can’t accurately reflect the value of the measured current. Since the optical current transformer noise inside the band is basically where the measured current signal overlap,we can not use the traditional method to filter it out ...
