Abstract
A magnetic resonance spectrometer in which an analog-to-digital converter in the receiving branch converts the spin resonance signals, or a spin resonance signal transposed to a lower frequency range, into a digital signal, and in which a Fourier transformation circuit is located in a signal path subsequent to the analog-to-digital converter. The signal path between the analog-to-digital converter and the Fourier transformation circuit includes at least one combination of a digital filter and a sampling frequency reducing circuit. The output signal of the reducing circuit has sampling frequency which has been reduced by an integer factor with respect to its input signal and, the reduced sampling frequency is a non-integer factor lower than the frequency of the signal on the output of the digital filter.
