A Preferable Method on Digital Filter in ECG Signal's Processing Based on FPGA
2010 Third International Symposium on Intelligent Information Technology and Security Informatics, 2010Digital filter is one of the most important components in electrocardiogram (ECG) signal’s processing. This research method combined Fast Fourier Transform (FFT) & Wavelet Threshold De-noising (WTD) to meet the demand that the ECG signal’s sampling and processing must be exact, real-time and steady. Meanwhile, the high performance of Field Programmable

Robust, Automated Methods for Filtering and Processing Neural Signals
2013This dissertation presents novel tools for robust filtering and processing of neural signals. These tools improve upon existing methods and were shown to be effective under a variety of conditions. They are also simple to use, allowing researchers and clinicians to focus more time on the analysis of neural data and making many tasks accessible to non ...

A method for speech signal processing based on band filtering of the logarithmic spectrum
Automation and Remote Control, 2014We 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 ...

An improved method for speech signal processing based on adaptive filter
2014 IEEE International Conference on Communiction Problem-solving, 2014Based 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 ...

Application of Wavelet Filter Method in Optical Tweezers Signal Processing
Advanced Materials Research, 2013One 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, 2015Optical 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 ...
