Genomic Signal Processing Methods in DNA Mapping Schemes for Prediction of Exon in a Gene Using Digital Filters

International Journal for Electronic Crime Investigation, 2023
Genomic signal processing (GSP) is an engineering domain involved with the analysis of genomic data using digital signal processing (DSP) approaches after transformation of the sequence of genome to numerical sequence. One challenge of GSP is how to minimize the error of detection of the protein coding region in a specified deoxyribonucleic acid (DNA ...

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.

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, 2010
Digital 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, 2018
In 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, 2010
Liquid 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, 2018
Absolute 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 $$2{-}3\,{\upmu }\hbox {Gal}$$

Application of the Wiener filtering algorithm for processing the signal obtained by the TDLAS method using the synchronous detection technique for the measurement problem of ¹³CO₂ concentration in exhaled air

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 to improve the performance of the LMS adaptive filter in processing signals of non-zero mean with sharp changes

1991 IEEE International Symposium on Circuits and Systems (ISCAS), 1991
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.
