Considering that the NQR response is very weak and there is very serious ringing interference,an adaptive filter is designed to eliminate the ringing by utilizing the correlation of the interference,then the NQR signal is extracted from background interference.

Analysis of Causes for Delay Phenomenon in Determining Carbon and Sulfur Content in Ferroalloy with High Frequency Carbon/Sulfur Determinator;

LCDs have "smearing" phenomenon all along.

Application of Heuristic Evolving Latent Projection(HELP) in the Resolution of Tailing Coeluting Chromatograms;

Transportation principle and mechanism, tailing mechanism of VOCs existing phase, non vapor and vapor VOCs when liquid VOCs goes into soil was studied.

The ringing problem in digital control for this kind of process was discussed,then a concrete form of the desired closed-loop transfer function was proposed,based on which the structure of the digital controller was obtained.

Signal integrity in the circuits design is discussed in this paper,and the major influencing factors are analyzed such as ringing,border distortion,reflection,bounce,crosstalk and jitter.

At the same time it can also eliminate the ringing phenomena of the controllers.

Aimed at detection of explosive,based on the theory of NQR detection,it is introduced that how the ring of the antenna(is produced in the NQR detection system and how important is to suppress the ring.
