Work is about substantiation of mathematical model of high resolution rhythmocardio signal in the form of a vector of stationary and stationary related random sequences. Investigated the structure of probabilistic characteristics of this model for analysis of cardiac rhythm in modern cardiodiagnostic system. Based on a new mathematical model of vector rhythmocardiosignals,was developed methods for statistical evaluation of their spectral-correlation characteristics, which are used as diagnostic features in automated diagnostic systems for functional diagnostics of the heart condition and adaptive regulatory mechanisms of the human body

A pre-classification method and its digital signalprocessing algorithm implemented by short time Fourier Transform for Chinese voiceless consonant speech are proposed. The important features of spike fill of stops,and C-V(C denotes voiceless consonant) boundary are detected and marked automatically ***,the Chinese voiceless consonants are divided into stops and non-stops according to these distinctive *** stops are further divided into unaspirated stops, aspirated-fricative *** on a data set of 910 C-V syllables from a database of 1267 Chinese all-syllable tokens spoken by a male speaker shows that the algorithm performs well,with a 92.4%average correct *** proposed method and algorithm are of value to impro\e the mechanism and performance of Chinese speech recognition system.

A lot of works have been done on Electrocardiogram and Phonocardiogram (ECG and PCG). But in most of the cases data for ECG or PCG have been taken from standarddatabase Iike MIT-BIH Arrhythmia or any other sourees. In this work a real-time signalprocessing task (RTST) on heart sound is presented. In the first part it is shown that the phonocardiogram signal (PCG) could be detected using an electronic circuit along with the DSP (TMS320C6713) processor from human heart. In the second part reduction of PCG signal and analysis of PCG signal have been shown using different digital signalprocessing techniques Iike Decimation, Interpolation, Windowing, Discrete Fourier Transform, Fast Fourier Transforms etc. In this work we have applied the Multi-rate signalprocessing Technique to reduce the size of the heart sound signal. The MSPT deals with different sampling frequencies. The challenging part of this work is to apply the DSP KIT to achieve the heart sound data and to apply the different signalprocessing techniques to reach the goal. An electronic circuit is designed and implemented along with a stethoscope to receive the heart sound signal (PCG signal) from the human heart. The DSP KIT is incorporated to proceed to the main work. The task has been completed through taking near about 20 person's real time heart sound samples (PCG samples).
Defect detection is an important part of industrial signalprocessing that uses various techniques to identify abnormalities in signals. This is done by using a combination of feature extraction, signal analysis, and ...
