erties of chaotic nonlinear dynamical systems ought to be taken into account, and, in fact, mayoften be exploited to achieve improved performance. For instance, because the evolution of chaoticsystems is acutely sensitive to initial conditions, it is often important that this numerical instabilitybe[r]

1999 by CRC Press LLCTo construct these criteria, a family of probability densities, f(Y|θ(Ns)), Ns= 0, ..., M − 1,is needed, where θ, which is a function of the number of sources, Ns, is the vector of parametersneeded for the model that generated the data Y. The criteria are composed of the[r]

Roughly speaking, a speech signal can be classified as voiced or unvoiced . Voiced sounds are generated when the vocal cords vibrate in such a way that the flow of air from the lungs is interrupted periodically, creating a sequence of pulses to excite the vocal tract. With the vocal cords stati[r]

Khi tiến vào thời đại kỹ thuật số, nhiều người trong các lĩnh vực khác nhau là khá quan tâm để hiểu tại sao điều này đã xảy ra. Họ hy vọng sẽ có được những nguyên tắc cơ bản về tín hiệu kỹ thuật số và hệ thống kỹ thuật số liên quan. Thay vì nhắm mục tiêu nâng cao trình độ hay chuyên gia, họ thường h[r]
