ABSTRACT:
A method and apparatus for generation of high frequency pulses and for excitation of nuclear magnetic resonance of a sample generates a plurality of modurated high frequency waves having different frequencies from each other, and combines the generated these high frequency waves so as to generate high frequency pulses which provide a frequency spectrum having a predetermined band, thereby a shortening of the high frequency pulse width as well as a narrowing of the frequency band is achieved.
