  • A spectral estimator of vocal jitter 

    Mas Soro, Pol (Universitat Politècnica de Catalunya, 2011-09-09)
    Master thesis (pre-Bologna period)
    Open Access
    English: The purpose of this thesis is to study and implement a spectral method for short-time jitter estimation. Jitter consists in rapid perturbations of the vocal cycle lengths, which can be observed from one cycle to ...
  • DLL's behavioral modeling for power consumption and jitter fast optimization 

    Barajas Ojeda, Enrique; Mateo Peña, Diego; González Jiménez, José Luis (2010)
    Conference report
    Open Access
    This paper analyzes the sources of jitter in a DLL and presents a behavioral model for fast DLL optimization. An algorithm to simulate the DLL in open loop is demonstrated. This procedure, together with the behavioral ...
  • Jitter and Shimmer measurements for speaker diarization 

    Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (2014)
    Conference report
    Open Access
    Jitter and shimmer voice quality features have been successfully used to characterize speaker voice traits and detect voice pathologies. Jitter and shimmer measure variations in the fundamental frequency and amplitude ...
  • The noise performance of a high-speed capacitive-sensor interface based on a relaxation oscillator and a fast counter 

    Gasulla Forner, Manuel; Li, Xiujun; Meijer, Gerard C. M. (Institute of Electrical and Electronics Engineers, 2005-10)
    Open Access
    This paper presents the analysis and experimental results on the noise performances of a capacitive-sensor interface. The interface is able to measure low capacitance values in the order of picofarads and is implemented ...
