ABSTRACT:
The nuclear resonance signal obtained from the sample is stored in a memory circuit and the stored signal is then repeatedly read out. A periodic function which is derived as a result of the transformation of a triangular wave into a trapezoidal one, is used for the Fourier transformation of the repeatedly read-out signal. The adverse influence of the transient phenomenon in the h-f impulse signal on the resultant spectrum is eliminated by stopping the Fourier transformation only during the initial portion of the read-out period of the memory circuit.
