  Jitter Estimation in Voice

  By Taru Aggarwal, Sharda Vashisth

  Abstract: Jitter is present in brisk perturbations of the vocal cycle lengths and when they are sampled at least at the rate of fundamental frequency they can be observed from one cycle to the next .Voice quality estimation can be done by analyzing jitter since it provides a high association with voice disorders. It also explains the variance of pitch keeps in the allowance of just noticeable difference, which can be …

  Ventricular Arrhythmia Detection Techniques for ECG Signal: A Survey Approach

  By Taru Aggarwal, Sharda Vashisth

  Abstract: Electrocardiogram (ECG) represents the electrical activity of the heart and is used to measure the rate and regularity of heartbeats. In this paper we propose a method for an Independent Component Analysis (ICA) based detection and classification of the ventricular arrhythmia. The malignant ventricular arrhythmia database from www.physionet.org/physiobank/database/vfdb has been utilized for evaluating the algorithm over MATLAB interface. This scheme assimilates ICA and probabilistic neural network for classifying critical arrhythmia …
