differential phase

However, the differential phase between legs has a very dramatic effect on the stereo image.

If the motion exceeds the differential phase, disintegration will result.

For example, a differential phase of 10 introduces an additional gain loss of 2%.

An alternative approach is the retrieval of the differential phase by using Moiré fringes.

Differential phase is a kind of linearity distortion which affects the color hue in TV broadcasting.

Consequently, landlines used by broadcasters for stereo transmissions are equalised to very tight differential phase specifications.

So the phase differences between two consecutive lines (so-called differential phase) are converted to differential gain distortions.

Only in that case a sufficient large Differential Phase Detection (DPD) tracking signal is generated.

Unlike the differential reflectivity, correlation coefficient and linear depolarization ratio, which are all dependent on reflected power, the specific differential phase is a "propagation effect."

Video requires a wider bandwidth and tighter differential phase specification which in turn results in a tighter dimensional specification for the cable.

Differential phase distortion (DP or dP) is the shift of color signal phase with respect to the colorburst phase.

To solve the problem of differential phase distortion in PAL system, the polarity of both the colorburst and the color signal are reversed in each consequative frame.

Differential phase shift keying (DPSK) is a common form of phase modulation that conveys data by changing the phase of the carrier wave.

By recording several images at different detuning angles, meaning at different positions on the rocking curve, a data set is gained which allows the retrieval of quantitative differential phase information.

Specific Differential Phase (θ) - The specific differential phase is a comparison of the returned phase difference between the horizontal and vertical pulses.

The resulting differential phase shift is measured through interferometry, thus translating one component of the angular velocity into a shift of the interference pattern which is measured photometrically.

For those media in which the amplitudes are unchanged but a differential phase delay occurs, the Jones matrix is unitary, while those affecting amplitude without phase have Hermitian Jones matrices.

Since the transverse shift of the interference fringes is linear proportional to the deviation angle the differential phase of the wave front is measured in GBI, similar as in ABI.

Strictly speaking, it's encoded in the change of the phase (differential phase shift keying): an unchanged phase in the beginning of a pixel means white, and a reversed phase means black.

Using this approach, the spatial resolution is lower than one achieved by the phase-stepping technique, but the total exposure time can be much shorter, because a differential phase image can be retrieved with only one Moiré pattern.

Reception problems can degrade an NTSC picture by changing the phase of the color signal (actually differential phase distortion), so the color balance of the picture will be altered unless a compensation is made in the receiver.

This problem has been solved either by recording differential phase contrast images of the sample in both direction x and y by turning the sample (or the gratings) by 90 or by the employment of two-dimensional gratings.

The recorded intensity oscillation can be represented by a Fourier series and by recording and comparing these intensity oscillations with or without the sample the separated differential phase shift and absorption signal relative to the reference image can be extracted.

Further, Nanotron's implementation can work at data rates of up to 2 Mbit/s - higher than specified in 802.15.4a. Finally, the IEEE 802.15.4a PHY standard actually mixes CSS encoding techniques with differential phase shift keying modulation (DPSK) to achieve better data rates.
