Basic concepts of signals, noise, and extraction of data from noisy signals are presented as an e-learning module. Excel spreadsheets allow students to vary noise parameters. Basic electronics ideas relating to RC circuits support introductory information on filtersThe website is available here .
This site provides two useful resources for instructors and students of analytical chemistry. The first is a collection of LabVIEW virtual instruments (VIs) for demonstrating topics such as signal-to-noise ratios, boxcar and ensemble averaging, power spectra, digital filtering, analog-to-digital conversions, and the Nyquest frequency. For users that do not have a working copy of LabVIEW, executable…
