noise criterion
2.At first, the tracking error within the whole trajectory is estimated according to the dynamic model of a PIGA. Secondly, the least-squares estimation of the parameters of the pulse transfer function and the philosophy of determining the order of the MA (moving average) noise with AIC criterion are described.
4.Multiple Criterion Optimization Design of the Low-Noise Broad-Band MMIC FET Amplifiers
5.Recently, it is due to the limitation of design on variable air volume air conditioner, the absence of effective vibration isolation system on the fixing of vantilation equipment and the maladjustment of air volume in the air channel, that the noise and vibration is in excess of the criterion, and much more economice dissension is solicited.
6.The character of EHV transmission line fault arc and its transient current is discussed, and the principle of non unit current transient protection is studied. Based on the time frequency localization and de noise character of wavelet transform, a new non unit current transient protection criterion based on multi resolution analysis is established.
