1, Patterns of in-phase and out-of-phase voltage and current signals can be utilised to recognise and in some circumstances correct for Groningen effects.

2, Through installing inphase(I) channel and quadrature (Q) channel, the effect of the carrier can be eliminated in NDLL. Therefore, the noncoherent demand of NDLL is satisfied.

3, Two companies—InPhase Technologies in Longmont, Colo. , and Optware in Yokohama, Japan—plan to release the first holographic drives for professional backup storage and archiving next year.

4, Quardrature sampling is, in fact, sampling in Radar's echo signal to produce the inphase components I(n) and quadrature components Q(n).

5, The function of vibrator's phase control system is to make the generated seismic signal inphase with reference signal.

6, The design of the communication and controlling circuit that transmits DTMF code in AC220 inphase power line is presented. It forms a complete system with data picking and processing circuit.

7, Output force phase should be controlled so as to get the far field signal inphase with the output force phase.
