Abstract:
A method for transforming an NMR signal (F.sub.k) acquired at one sample rate (1/.DELTA.t.sub.A/D) into an output NMR signal (G.sub.j) of a prescribed sample rate (1/.DELTA.t), the steps comprising:a) calculating a weighting function (W.sup.k.spsp.2) based on the one sample rate, the prescribed sample rate and the total number of acquired samples (M);b) producing a windowed NMR signal (G.sub.k) by multiplying the Fourier transform of the NMR signal (F.sub.k) with a window function (H.sub.k);c) multiplying the windowed NMR signal (G.sub.k) by the weighting function (W.sup.k.spsp.2);d) convolving the result of step c) with the complex conjugate of the weighting function (W.sup.k.spsp.2); ande) producing the output NMR signal (G.sub.j) by multiplying the result of step d) with the weighting function (W.sup.j.spsp.2).
