When the phase reversal is detected, the echo cancellers are disabled.
The modulation is based on phase modulation, such as binary-phase-shift-keying (BPSK) or phase reversal keying (PRK).
A phase-sensitive rectifier (PSR) system uses phase reversal modulation (PRM) to remove the effects of offsets.
The apparatus is arranged so that a detectable phase reversal occurs as the object crosses the plane.
A T-wave alternans phase reversal is detected in response to comparing the first difference and the second difference, and the patient's arrhythmia risk is classified in response to detecting the phase reversal.
In this way, phase inversion is effectively prevented.
A double inversion amounts to cancellation of the primary natural effect combined with a natural effect of a systematic phase inversion.
Also disclosed is a phase inversion method for manufacturing the membrane.
Porous membranes preparation by phase inversion process
The loaded nanospheres are e.g. made by phase inversion.
phase change signaling system
phase change signalling system
The signal (12) is modulated by a phase shift keying method in such a manner that the change (27) of a bit in the date (26) is encoded by the rapid change in phase in the manner of a phase shift (28) of the carrier wave (25).
The at least one signal (12) is modulated by a phase shift keying method in such a manner that the change (27) of a bit in the date (26) is encoded by the rapid change in phase in the manner of a phase shift (28) of the carrier wave (25).
The phase rotation sequence may include changing phase once per slot, or alternately once per frame.
A signal which is phase inverted in relation to the indicated voltage variations is generated.
The subject phase invertable compositions are prepared by combining a proteinaceous substrate and a cross-linker.
Phase inversion microporous membranes including at least two different pore size regions are provided, wherein two membrane sheets are placed, back-to-back, such that the qualifying pore zones are positioned internally within the structure.
The nascent hollow fiber is coagulated in a coagulant bath to effect phase inversion of the polymeric binders.
The difference signal is phase inverted to obtain an inverted difference signal.
Membranes are formed from polybenzimidazoles by phase inversion and are then crosslinked by addition of crosslinking agents.
This inverted difference signal is combined with the input signal to provide a corrected input signal.
Biocompatible phase invertable proteinaceous compositions and methods for making and using the same are provided.
The apparatus determines the phase -inverted signal component that corresponds to the signal component being proximate to the source (312-332).
The invention relates to a solvent-resistant PAN membrane, especially for ultra- and nanofiltration.
