Abstract

PURPOSE: To realize an accurate recording for the resonant spectrum in the minimum necessary time, by setting the recording speed in accordance with the window function which is multiplied by the Fourier conversion nuclear magnetism resonant spectrum in order to improve the S/N and the resolution.

CONSTITUTION: The S/N and other factors are improved for the Fourier conversion nuclear magnetism resonant spectrum by multiplying a large value by the signal part and a small value by the noise part via the fixed window function of the exponent function type and in order to increase the sensitivity. Such resonant spectrum is stored in the memory part 1 and receives a D/A conversion after stored temporarily into the latch circuits 3 and 4 according to the address given from the decoder circuit 9, and then recorded on the recorder 5. In that case, the recording speed is controlled so as to obtain the set recording time TX which is based on the equation I and others corresponding to the different window function selected in accordance with improvements of the S/N, the resolution, etc. As a result, the resonant spectrum having the improved S/N or resolution can be recorded accurately in the minimum necessary time. Here K means the window function.
