phase shift

in nuclear magnetic resonance, the change in phase caused by movement of the spins, which can be used to show fluid flow.

phase shift

An alteration in the time relationship between the peaks (or troughs) of two different periodic functions. Thus, two circadian rhythms may suffer a phase shift as in jet lag.

[delta] is an additional phase shift introduced to the reference wave, which is controlled by the PZT element.
We have investigated the phase shifts due to four different measured action currents, from the frog sciatic nerve, the crayfish medial giant axon, the squid giant axon, and the human median nerve.
Coral reefs can undergo fast changes in their dominant life forms, a phenomenon referred to as phase shift.
The purpose of the phase shifter is to maintain a total phase shift of 360[degrees] in the loop, so that oscillations can occur.
The dependence of the phase shifts on the cutoff is replaced by a dependence on the subtraction point that can be later eliminated by using the renormalization group flow.
The second and third parts represent phase shifts of the carrier signal in radians as follows: MODULATOR represents a phase shift of the outgoing signal from a modulator and DEMODULATOR represents a phase shift of the signal after passing through a model of the optical transmission path.
There is high probability that this exceptional high number of outliers (14%, nowhere else found) can be reduced considering a phase shift 6; or different phase shifts [delta] can put the elementary particles into different groups.
For large phase shifts, a broadband switched line/reflected bit topology is used (Figure 2).
Using a skew symmetrical perfect crystal Si-interferometer and a linear twin chamber cell, false phase shifts due to sample misalignment were reduced to a negligible level.
In this case, the even- and odd-modes of the coupled microstrip line have the differential phase shifts.
[13] and [15] we know that the dynamical part stemming from the phase shifter PS2 is given by a weighted sum of the phase shifts [[phi].sub.1] and [[phi].sub.2] with the weights depending on the transmission coeficient T.
Electronic line stretchers offer controlled phase shifts over wide frequency ranges to simplify once tedious VCO measurements.
