As the value of scaling factor α = 2, i.e., α > 1, thus there is the time compression of the signal and the compressed signal is shown in Figure-2. Here, it can be seen that the time compressed signal x(2t) increases linearly from 0 to 5 in the time interval 𝑡 = − (...

Basing on presented idea one can form the voltages and currents in linear and nonlinear electric circuits as well as other "output" signals in technical systems with lumped parameters.Grzywacz, B.Electrotechnical Conference, 2006. MELECON 2006. IEEE Mediterranean...
In discussing the theory of discrete-time signals and systems, several basic se- quences are of particular importance. These sequences are shown in Figure 2.3 and will be discussed next. The unit sample sequence (Figure 2.3a) is defined as the sequence δ[n] = 0, 1, n = 0, n = 0...
In this chapter, we present the basic definitions, establish notation, and develop and review the basic concepts associated with discrete-time signals and systems. The pre sentation of this material assumes that the reader has had previous exposure to some of this material, perhaps with a ...

High quality time-scaling and pitch-scaling of audio signals In one alternative, an audio signal is analyzed using multiple psychoacoustic criteria to identify a region of the signal in which time scaling and/or pitc... BG Crockett 被引量: 85发表: 2009年 An audio decoder for providing decoded...
systems, as well as instruments to guarantee them in practice, including the Lyapunov–Krasovskii, Lyapunov–Razumikhin, and Halanay approaches. We then consider the influence of inputs through the notions of ISS, integral ISS, and input-to-output stability and provide both Lyapunov-like and ...
Magnitude and sign scaling in power-law correlated time series A time series can be decomposed into two sub-series: a magnitude series and a sign series. Here we analyze separately the scaling properties of the magnitu... Yosef,Ashkenazy,and,... - 《Physica A Statistical Mechanics & Its Ap...
