Filter for Processing of NMR Signal
One of the fields of science,where is going forward continual development,is the area of nuclear magnetic resonance(NMR).Bulk of the NMR issues concerns on signal processing in analog and digital form in NMR signal.In this paper is focused our attention on design of active analog filter with frequency dependent negative resistor(FDNR).There is designed active ARC filter based on ladder structure of the LRC filter,then the filter DCR is made through the use of Brutton transformation and finally the DCR filter is converted to the filter with FDNR elements.The designed and realized filter is used as a low pass filter,which aims to filter out the noise of NMR signal.The filter is placed behind the mixer,which converts the useful NMR signal to baseband.The designed and realized filter performs role of the anti-aliasing filter before the A/D converter.
