✦ Synopsis

A data handling procedure is proposed for improving the signal-to-noise ratio in remote nuclear quadrupole resonance spectroscopy, which involves high-speed A/D conversion and data averaging in the time domain, it is demonstrated by experimental results that, with the suggested procedure, the S/N may be enhanced by a factor of about 5 in remote NOR where the bandwidth of the receiver is fairly broad. In addition to its simplicity, the procedure can be used for real-time digital filtering the FID signal.

## Abstract Moving average can be used to improve the signal‐to‐noise ratio of NMR kinetic studies. The method was tested on simulated spectra with time‐dependent intensities or peak positions. It was then applied to a series of __in vivo__ spectra, showing the pharmacological effect of heptaminol

## Abstract In sensory biology, a major outstanding question is how sensory receptor cells minimize noise while maximizing signal to set the detection threshold. This optimization could be problematic because the origin of both the signals and the limiting noise in most sensory systems is believed
