The basic model for the waveguide uses a delay line of p samples which determines the resonant frequency of the string, a low-pass filter which simulates the energy loss caused by the reflection of ...

Wütrich in 2002 (chemistry), and P. Lauterbur & P. Mansfield in 2003 (medicine). The utility of NMR stems from the fact that chemically distinct nuclei differ in resonance frequency in the same ...
