摘要
In the present study, the wavelet transform is used to increase the signal-to-noise ratio of nuclear quadrupole resonance (NQR) signals in the direct pulse method. The efficiency of the wavelet and Fourier transforms used for detecting the NQR signal component is compared. The signal consists of noise, magnetoacoustic and piezoelectric signals, noise from external sources, and NQR signal. Signals from 14 N nuclei in hexahydro-1,3,5-trinitro-s-triazine C 3H 6N 6O 6 (RDX) are investigated at a temperature of 298 K. ©2005 Springer Science+Business Media, Inc.
