Original Abstract

Removing noise from an free induction decay (FID) signal is of fundamental significance in the analysis of results of magnetic resonance (MR) spectroscopy and tomography. Optimum solution can be seen in removing noise by means of a digital filter bank that uses half-band mirror frequency filters of the type of low-pass and high-pass filters. A filtering method using digital filters and the approach threshold adjustment is described in the paper.
