Jc. Liu et al., IMPROVED DIFFERENTIAL AVERAGING TECHNIQUE FOR COMPARISON DECREMENT METHOD, IEE proceedings. Microwaves, antennas and propagation, 144(5), 1997, pp. 377-381
The comparison decrement method is generalised to apply in both time-d
omain and frequency-domain analysis. Experimental results are presente
d to verify. The sensitivity of Q-factor measurements can be improved
by using the differential averaging technique. High-Q ceramic material
s Ba3ZnTa2-xNbxO9, Ba3MgTa2-xNbxO9 and Ba3Zn1-xMgxT2O9 and also the Sr
3ZnTa2-xNbxO9, Sr3MgTa2-xNbxO9, Sr3Zn1-xMgxT2O9 family are measured an
d introduced.
