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

Communication Signal Pre-Processing in Impulsive Noise: A Bandpass Myriad Filtering-Based Method
IEEE Communications Letters, 2018In impulsive noise modeled as symmetric $\alpha $ -stable ( ${\mathrm{S\alpha S}}$ ) distribution, it is known that signal processing techniques performed in bandpass can generally achieve better performance than in baseband. In this letter, we propose a bandpass myriad filtering-based pre-processing method for a communication receiver in ${

Subsection-filtering method applied in optoelectronic signal processing of the liquid drop analyzer
SPIE Proceedings, 2010Liquid drop fingerprint can be obtained through fiber-capacitive drop analysis technology as the fiber signal changes with the drop volume which can be represented by the capacitive signal during the drop growth. However, if the fiber or capacitive signals are filtered by the normal low-pass filter method, the fingerprint would be distorted because ...

FFT swept filtering: a bias-free method for processing fringe signals in absolute gravimeters
Journal of Geodesy, 2018Absolute gravimeters, based on laser interferometry, are widely used for many applications in geoscience and metrology. Although currently the most accurate FG5 and FG5X gravimeters declare standard uncertainties at the level of $$2{-}3\,{\upmu }\hbox {Gal}$$

Laser Physics Letters, 2019
It has been shown clearly that using the synchronous detection technique with the pump current frequency modulation of a tunable diode laser emitting near 2 μm wavelength, combined with the application of the Wiener filtering algorithm for the experimental signal, ensures a two-times improvement in the measurement accuracy for the 13CO2 content in ...

A method is proposed to improve the performance of the conventional least-mean-square (LMS) adaptive filter in processing signals of nonzero mean with abrupt changes. It is theoretically determined that, with the aid of a local-mean estimator (LME), the working condition and thus the performance of the adaptive filter can be improved.
