Originální abstrakt

The paper deals with the design of low-pass filter with lossy FNDR element. The purpose of the using the filter is as anti-aliasing filter in NMR spectrometer signal path. Signal of resonant nucleus detected by probe can be expected at uV level. Low noise preamplifier will increase the level of NMR signal before mixer. The mixer bring useful signal to base band. Inter frequency signal required to be filtered by low-pass filter with appropriate order. There is possible to use Bessel or Butterworth approximation. Filter has to have low noise parameters. In general, noise parameters are the most signifcant in all signal path design.
