APPLICATION OF THE FOUR DDS DEVICES RUNNING IN PARALLEL TO NMR

Frequency synthesizer is an important part in Nuclear Magnetic Resonance (NMR). With rapid development of micro electronics technology, Direct Digital Synthesizer (DDS) becomes possible. Application of DDS to NMR spectroscopy has been successful, but it is generally limited to low frequency range. In order to solve the difficulty, we studied and designed a frequency synthesizer, which involves multiple DDS chips running in parallel.
