Compression in the Time Domain

American Journal of Audiology, 1993
High input levels can cause saturation and "fast pumping" effects in hearing aids. The resulting distortion products and changes in speech amplitude envelope are examined in the time domain. Spectrograms reveal changes in speech elements not apparent with time domain methods.

Time-domain tests for Gaussianity and time-reversibility

IEEE Transactions on Signal Processing, 1994
Statistical signal processing algorithms often rely upon Gaussianity and time-reversibility, two important notions related to the probability structure of stationary random signals and their symmetry. Parametric models obtained via second-order statistics (SOS) are appropriate when the available data is Gaussian and time-reversible.

Optical time domain reflectometer

Applied Optics, 1977
By using an optical time domain reflectometer a new measurement technique which allows displaying the length dependence of the fiber attenuation by analyzing backscattered light has been developed. This paper compares the backscatter and insertion-loss techniques.

Time-domain Oustaloup approximation

2015 20th International Conference on Methods and Models in Automation and Robotics (MMAR), 2015
Paper presents a new method for implementing Oustaloup approximation of non-integer order systems in digital environment. Classical method and its limitations are presented and discussed. Method of realization is formulated and schemes for discretization are presented. Operation of method is illustrated with two examples.

Analysis of accumulated timing-jitter in the time domain

IEEE Transactions on Instrumentation and Measurement, 1998
This paper deals with the effects of accumulated timing-jitter on the signal-to-noise ratio (SNR) of real sine waves. Such a problem was recently investigated by the author, using the discrete-Fourier method. However, the frequency-domain analysis has some limitations due to the fact that some of the accumulated timing-jitter noise power, found at the ...

Time domain right invertibility

2006 American Control Conference, 2006
Generalized systems (also called implicit, descriptor, etc.) usually offer more possibilities for solving control and observation problems. In this context, we use an important tool of System Theory, namely right invertible systems. In this paper we consider some possible dualizations results on time domain left invertibility and point out which ...

On frequency-domain and time-domain phase unwrapping

Proceedings of the IEEE, 1987
Time-domain phase unwrapping of analytic or complex functions of time is an unavoidable operation when processing such signals within an FM-modeling framework or when attempting to establish the instantaneous frequency of such signals. With the help of an alternate derivation of his equations, Tribolet's frequency-domain phase unwrapping algorithm is ...

Electrical neuroimaging in the time domain

2009
A publication entitled “A default mode of brain function” initiated a new way of looking at functional imaging data. In this PET study the authors discussed the often-observed consistent decrease of brain activation in a variety of tasks as compared with the baseline.
