The accurate interpretation of in vivo magnetic resonance spectroscopy (MRS) spectra requires a complete understanding of the associated noise-induced errors. In this paper, we address the effect of complex correlated noise patterns on the measurement of a set of peak parameters. This is examined in

This paper presents the results of studies on high stability oscillators with superconducting resonance systems incorporated, which operate at superhigh and radio frequencies. A superconducting resonance system was also used to build a mode/superconducting gravimeter of 10-log sensitivity.
## Abstract In __in vivo__ MR spectroscopy studies, it is desirable to determine metabolite peak parameters with good precision and to estimate the uncertainties. How to achieve optimal precision for an apodized MR spectrum by using a weighted least squares estimator is discussed and demonstrated.
