    Wavelet Denoising of NMR Signal Using QMF Filer Bank Designed by Remez Algorithm

  • Original language description

    The wavelet transform is an up-to-date method for digital signal processing used in many branches of technology. One of its applications is the suppression of noise in useful signal. The paper deals with suppressing noise in a signal scanned on the NMR tomograph. The method of sub-band thresholding using the wavelet transform is discussed. This method is used in double denoising filtering of an FID signal and an instantaneous frequency signal. Using a filter bank with uniform ripple, designed by the Remmez algorithm, is of advantage.

    Waveletovská protišumová filtrace pomocí QMF banky filtrů navržené Remezovím algoritmem.

  • Czech description

    Odstranění šumu z užitečého signálu je velmi žádaná technika v mnoha technických odvětvích. Waveletovská filtrace je jednou z nejúčinnějších metod, přičemž použití QMF banky filtrů s rovnoměrným zvlněním se ukázalo jako velmi výhodné.
