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

Phase Distortion and Phase Distortion Correction

Bell System Technical Journal, 1928
The importance of the rocle played by the steady state phase characteristics of long cable circuits has recently been emphasized in telephone and telegraph transmission. In this paper an analytical exposition of the theory of phase distortion is followed by a consideration of various methods of phase distortion correction with particular reference to ...

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.
