The information capacity of the human motor system in controlling the amplitude of movement.

Journal of Experimental Psychology, 1954
Information theory has recently been employed to specify more precisely than has hitherto been possible man's capacity in certain sensory, perceptual, and perceptual-motor functions (5, 10, 13, 15, 17, 18).

Speech enhancement using a minimum mean-square error log-spectral amplitude estimator

IEEE Transactions on Acoustics Speech and Signal Processing, 1984
In this correspondence we derive a short-time spectral amplitude (STSA) estimator for speech signals which minimizes the mean-square error of the log-spectra (i.e., the original STSA and its estimator) and examine it in enhancing noisy speech.

A Model for Collision Processes in Gases. I. Small Amplitude Processes in Charged and Neutral One-Component Systems

, 1954
A kinetic theory approach to collision processes in ionized and neutral gases is presented. This approach is adequate for the unified treatment of the dynamic properties of gases over a continuous range of pressures from the Knudsen limit to the high ...

Speech enhancement using a minimum mean square error short-time spectral amplitude estimator

, 1984
Absstroct-This paper focuses on the class of speech enhancement systems which capitalize on the major importance of the short-time spectral amplitude (STSA) of the speech signal in its perception. A system which utilizes a minimum mean-square error (MMSE)

Amplitude-smoothed BPOF and amplitude-smoothed amplitude-encoded BPOF

SPIE Proceedings, 1990
In this paper smoothed binary phaseonly filtcr(ASBPOF) and amplitude smoothed amplitude encoded BPOF(ASAEBPOF) are presented. By computer simulation in the case of symmetrical and unsymmetrical characters it is concluded that with the BPOF and AEBPOF these filters sacrifice light efficiency due to the amplitudesmoothed factor it yield much better ...

On the utility of P3 amplitude as a measure of processing capacity.

Psychophysiology, 2001
The present review focuses on the utility of the amplitude of P3 of as a measure of processing capacity and mental workload. The paper starts with a brief outline of the conceptual framework underlying the relationship between P3 amplitude and task ...

High Efficiency Metasurfaces with Independent Control of Phase, Amplitude, and Polarization

IEEE Asia-Pacific Conference on Antennas and Propagation, 2018
Metasurfaces that can simultaneously manipulate amplitude and phase have attracted great attention and have great application prospects due to their powerful beam steering capabilities.

Amplitude density of a finite amplitude wave

The Journal of the Acoustical Society of America, 1979
A theoretical analysis of the effect of nonlinear propagation distortion on the amplitude density of a sample noise signal in a lossless medium is given. It is found that under certain general conditions the amplitude density prior to shock formation is unaffected by the distortion.
