The goal set by Hans Primas was the usage of random noise for the excitation of nuclear magnetic resonance, following the famous concepts of Norbert Wiener for the stochastic testing of non-linear systems.Quote by Richard Ernst about purpose
We developed at that time also stochastic resonance as an alternative to pulse FT spectroscopy employing binary pseudo-random noise sequences for broadband excitation, correlating input and output noise.Quote by Richard Ernst about time
