Nuclear Magnetic Resonance, A New Approach to EMC

Nuclear magnetic resonance (NMR) has been utilized to provide a stable AM and FM modulated oscillator having far less undesired output, yet considerably greater versatility and frequency range than other sigal sources. This oscillator has been exhaustively studied in theory and experiment; however, only a brief but comprehensive review of theory as it interests the electronic engineer is given. The basic design of this oscillator is discussed along with the reasons why other NMR designs have failed.
