Detection of cracked-shell eggs using acoustic signal and fuzzy recognition;

When the running situation of a rotating machine becomes abnormal or a part of it does not work well,it usually generates a periodic vibration signal or a periodic acoustic signal,which generally are periodic impulse signals with relatively strong noise.

Through the features analysis of acoustic signals in time domain and frequency domain which is recieved,by giving a little force to the adhesive structure, can be extracted the features related to the adhesion.

Design of Sound Signal Acquisition System Based on DSP and USB;

In this paper,we investigated and analyzed the sound signals arisen during no-load planer operation.

In order to detect the rub-impact position, the paper bases on the way of combining sound signal with key-phase signal to fix on the position.

Data recall and analysis system of heart sounds and ECG signal based on LabVIEW;

In the course of recording heart sound, it is inevitable that many kinds of noise will be merged in the main signal.

In process of recording heart sound,it is inevitable that many kinds of noise will be merged in the main signal.

Bispectrum estimation and its application in analysis of heart sound signals;

Analysing heart sound signals using wavelet transform;

Study of Myocardial Inotropism and Chronotropism Based on Telemetering Heart Sound Signal;

Research on signal processing of heart sounds to diagnose coronary artery disease;

This paper described a new system for recording, processing and analyzing heart sounds.

This paper describs a new system for gathering heart sounds.

Method of solving LPC coefficients of speech signals;

the Character Analysis of Speech Signal with Time and Frequency Based on MATLAB;

Method to determine delay time of speech signal in reconstructed phase space;

This paper presents a new kind of collecting and processing system of the sound signal of larynx where double sound cards and software filter are used.

Blind source separation of speech signals based on the amplitude correlation of neighbour bins;

The Study of Blind Source Separation of Speech Signals;

Based on the analysis of average displacement (AD) method for selection of time delay in phase space reconstruction of speech signals, this paper modifies the original measurement of AD method to get a better criterion for proper time delay selection, which has a sound theoretic basis and can produce better effect.
