The biassed ferrite is part of the circulator and causes a differential phase-shift for signals travelling in different directions.
2.
When differential encoding is used in this manner, the scheme is known as differential phase-shift keying ( DPSK ).
3.
Since this scheme depends on the difference between successive phases, it is termed differential phase-shift keying ( DPSK ).
4.
Differential phase shift keying ( DPSK ) is a common form of phase modulation that conveys data by changing the phase of the carrier wave.
5.
As delivered, the physical layer is OFDM, sampled at 250 kHz, with 512 differential phase shift keying channels from 42 89 kHz.
6.
Since this scheme depends on the difference between successive phases, it is termed "'differential phase-shift keying ( DPSK ) " '.
7.
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 consecutive frame.
8.
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.
9.
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.
10.
So the phase differences between two consecutive lines ( so-called differential phase ) are converted to differential gain distortions . ( Hue is preserved at the risk of decreased saturation ).
