Phase distortions - Open Access .click

2011 XXXth URSI General Assembly and Scientific Symposium, 2011
In this paper we study the phase estimation problem in the presence of white noise and phase distortions on the basis of the Markovian technique of nonlinear processing of random fields. The emphasis is on the processing error dependence of the number of receivers.

PHASE INSTABILITIES OF DISTORTED HEXAGONAL PATTERNS

International Journal of Bifurcation and Chaos, 2001
We present an analytical study on the stability of distorted hexagonal patterns. From a general amplitude equation we calculate the instabilities with respect to homogeneous and longwave perturbations. The latter lead to the phase equations that permit to determine the stability regions. Slightly squeezed hexagons are locally stable in a full range of

Perceptual identification and discrimination of phase distortions

ICASSP '83. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Experimental results on the audibility of phase distortion produced by minimum-phase 4kHz and 15 kHz anti-alias filters are reported. Numerous impulse response pairs with identical spectral magnitudes but linear-phase and minimum-phase responses were compared by five test subjects who listened dichotically on earphones.

Measurement of Phase Distortion*

Bell System Technical Journal, 1930
This paper deals with the measurement of phase distortion or delay distortion and is particularly concerned with measurements on telephone circuits. For this purpose, use is made of a quantity defined as “envelope delay,” which is the first derivative of the phase shift with respect to frequency.
