Frequency and phase are defined using graphs and trigonometric equations. Properties of phase sensitive detectors are described, which are then used to show how they can be employed to receive NMR signals. The principles described here are needed to understand the block diagrams of NMR spectrometers shown in the next course.
Dr. Traficante obtained his Ph.D. in 1962 from MIT in the field of synthetic organic chemistry. He has worked in the NMR field since 1962, and in the early 1970s he pioneered multi-nuclear instrumentation. He has built probes, reassembled spectrometers, and developed new software programs to enhance the signal-to-noise ratio and the resolution of NMR spectra. His current research in the areas of structure determination, instrumentation, and data processing provide him with knowledge and expertise that are applicable to a broad audience. His organic chemistry background, plus his expertise in electronics, gives his lectures a special depth and appreciation for the field. Dr. Traficante is known throughout the world as an outstanding educator.
