A Method of Pre-processing Photoplethysmographic Signal Based on Adaptive Filter for Pulse Oximeter

2010 International Conference on Intelligent Computation Technology and Automation, 2010
Adaptive filter based on least-mean-square (LMS) algorithm is used to pre-processing photoplethysmography (PPG) signal which is feeble and apt to affect by motion artifact. Firstly, relationship between normal signal and motion artifact is analyzed using Beer-Lambert Law for settling motive interference problem of pulse oximeter.

Analysis of Digital Filter Prototype Design Methods for High-Speed Signal Processing Based on Polyphase Filter Bank

2019 Systems of Signals Generating and Processing in the Field of on Board Communications, 2019
This article presents a comparison of two methods for synthesizing digital filter prototypes. The first method based on the synthesis of the filter on a lattice structure, and the second iterative method based on minimizing the quadratic form. Both methods are applying with the fulfillment of the conditions of perfect reconstruction.

Vector Hilbert-Huang Transform signal processing based on scale filtering method

2011 4th International Congress on Image and Signal Processing, 2011
Hilbert-Huang Transform (HHT) is a kind of signal analysis method suitable for non-stationary signal, and the combination of HHT and vector signal processing is called vector HHT, by which the instantaneous azimuth of the target can be estimated. In vector HHT signal processing method, the existence of intermittent signal and noise leads to mode mixing

Further results on reconstruction methods for processing finite-length signals with perfect reconstruction filter banks

IEEE Transactions on Signal Processing, 2000
In de Queiroz and Rao (1995), new expressions were developed for the perfect reconstruction (PR) of the boundary regions of a finite-length signal after subband processing using uniform and paraunitary filter banks (PUFBs). The present paper points out an incorrect assertion in the previous paper regarding the sufficiency of its solution and presents ...

Application of High Frequency Signal Injection Method in Motor Control Using Kalman Filter for Signal Processing

2010
High frequency (HF) signal injection method is the most available method to achieve low speed and zero speed operations in mechanical sensor-less control of AC motors. The difficulty in HF signal injection method is how to pick up the HF components from the measured currents.

Apparatus and Method for Processing an Audio Signal using a Harmonic Post-Filter

An apparatus for processing an audio signal having associated therewith a pitch lag information and a gain information, comprises a domain converter (100) for converting a first domain epresentation of the audio signal into a second domain representation of the audio signal; and a harmonic post-filter (104) for filtering the second domain ...
