Abstrakt: NQR signal processing method based on two adaptive filters techniques namely adaptive noise cancellation (ANC), adaptive line enhancement (ALE) and wavelet transform are studied and it is shown that ALE is faster detection method with improved signal to noise ratio. Based on the 14N NQR signal observed from NaNO2, ALE seems to be easier and more reliable technique for NQR spectroscopy.
