Fundamental frequency

In this paper, the Finite Element Method (in ANSYS) is used to investigate natural frequency of vibration and bending characteristics under varying pressure loads applied on the top skin when changing fundamental properties of some gradient configurations, including angular gradient, thickness gradient and functional gradient configurations of the auxetic plate with honeycomb structure.

The overall performance of the systems is often limited by the accuracy of the underlying speech parameterization and reconstruction method. The method proposed in this paper allows accurate MFCC, F0 and tone extraction and high-quality reconstruction of speech signals assuming Mel Log Spectral Approximation filter. Its suitability for high-quality HMM-based speech synthesis is shown through evaluations subjectively.

Data can be analog or digital. The term analog data refers to information that is continuous; digital data refers to information that has discrete states. Analog data take on continuous values. Digital data take on discrete values.Data can be analog or digital. Analog data are continuous and take continuous values. Digital data have discrete states and take discrete values.

Short-Time Fourier Analysis A fundamental problem in signal analysis is to find the spectral components containedin a measuredsignal z ( t ) and/or to provide information about the time intervals when certain frequencies occur. An example of what we are looking for is a sheet of music, which clearly assigns time to frequency, see Figure 7.1. The classical Fourier analysis only partly solves the problem, because it does not allow an assignment of spectralcomponents to time. Therefore one seeks other transforms which give insight into signal properties in a different way. ...

Chapter 17, Solution 1. (a) This is periodic with ω = π which leads to T = 2π/ω = 2. (b) y(t) is not periodic although sin t and 4 cos 2πt are independently periodic. (c) Since sin A cos B = 0.5[sin(A + B) + sin(A – B)], g(t) = sin 3t cos 4t = 0.5[sin 7t + sin(–t)] = –0.5 sin t + 0.5 sin7t which is harmonic or periodic with the fundamental frequency ω = 1 or T = 2π/ω = 2π. (d) h(t) = cos 2 t = 0.5(1 + cos 2t). Since the sum of a periodic...

Organizations are discovering with increasing frequency that the vast majority of their information assets have a spatial component, for example, the location of customers, shipments, facilities, personnel, competitors, and so on. The ability to use this information properly is fundamental to reducing operational costs, optimizing production efficiency, and increasing the quality of service. Evidence of the benefits that can be achieved by exploiting spatial information is plentiful, and many organizations are looking at ways of harvesting these benefits....
