The harmonic parameters Autocorrelation, Harmonic to Noise Ratio (HNR), and are related vocal quality, providing alternative measures of the energy a speech signal. They will be used as input resources for an intelligent medical decision support system diagnosis pathology. An efficient algorithm is important when implementing it on low-power devices. This article presents that determines these ...

Digital filters are vastly utilized in the area of communication. A perfect digital filter efficiency is significant and hence to design a finite impulse response (FIR) favorable all wanted situations necessary. In this paper, new proposed FIR designed, fineness submitted tested terms BER then matched with another window, namely Hamming, Hanning, Blackman. The procedure done MATLAB software. It...

Background: In myocardial perfusion SPECT imaging, images are degraded by photon attenuation, the distance-dependent collimator, detector response and photons scatter. Filters greatly affect quality of nuclear medicine images Materials and Methods: A phantom simulating heart left ventricle was built. About 1mCi of 99mTc was injected into the phantom. Images were taken from this phantom. Some fi...

Cepstrum is an algorithm for analyzing the speech signals in frequency domain. This is conventional method of fundamental peak picking i.e. fundamental frequency or pitch. For a speech signal it is necessary to identify the fundamental frequency correctly in order to have robust system for speaker identification and verification. Using this approach two algorithms has been proposed using Hammin...

This paper proposed a class of polynomial window functions whose coefficients are optimized with the Enhanced Differential Evolution (EDE). Through optimization, the proposed window not only has an optimal solution, but can support different kinds of prescribed applications. The comparisons and analysis also show that the proposed method has a better performance than the traditional ones such a...
