During full operations two identical satellites will be maintained in the same orbit with a phase delay of 180 .
The direction of observation ("beam") is chosen electronically by phase delays between the antennas.
Equalizing filters must cancel out any group delay and phase delay between different frequency components.
So the auditory system can determine phase delays between both ears without confusion.
Our sensors are creating perfect inwerse phase delays to show there is nothing in the immediate wicinity.
They managed to broadcast a perfect phase delay to us so our sensors showed no return signal for a few seconds.
Their analysis shows that multipath effects exacerbate the difference between the observed phase delay and the group delay.
As the electrons move around energy levels, some energy is released as an electromagnetic wave at the same frequency but with a phase delay.
The tide heights are expected to follow the tidal force, with a constant amplitude and phase delay for each component.
However, these volunteers were allowed to control artificial lighting and the light in the evening caused a phase delay.
