phase shift

[′fāz ‚shift]
(electronics)
The phase angle between the input and output signals of a network or system.
(physics)
A change in the phase of a periodic quantity. Also known as phase change.
A change in the phase angle between two periodic quantities.
(quantum mechanics)
For a partial wave of a particle scattered by a spherically symmetric potential, the phase shift is the difference between the phase of the wave function far from the scatterer and the corresponding phase of a free particle.

Thus, the pure phase shift of the sample can be determined by compensating the phase of the reference wave, as shown in Fig.
All these phase shifts are very small, much less than one degree.
Scientists have speculated on many possible causes of phase shift, but this study is the first one to clearly show that a rapid change in the dominant life forms on a coral reef is associated with man-made structures.
In this work we employ the subtract kernel method to renormalize the Lippmann-Schwinger equation in N3LO and perform a detailed renormalization scale dependence analysis of the phase shifts in peripheral channels.
This paper deals with a modeling of the phase shift keying (PSK) modulation technique and its multi-level variations, which appears to be very resistant to nonlinear effects present in the optical transmission medium [4, 5].
An additional phase shift 6 was introduced in equations 5 and 6.
For moderate phase shifts, a broadband reflected bit topology is used (Figure 6).
Figure 4 shows the measured phase shifts of the individual measurements as a function of particle number area density.
Because of the nonreciprocity of the magnetized gyrotropic layer, the even- and odd-modes of the coupled microstrip lines have differential phase shifts as shown in previous sections.
which vanishes by an appropriate choice of phase shifts and transmission, i.
phase shifts across wide frequency ranges (see table).
