In this paper we have reviewed the basics of digital modulation and attempted to show why these modulation schemes are important to wireless data transmission. Spread spectrum was also reviewed showing how its deployment can further enhance a wireles

A procedure for estimation of the forcing functions on a turbine blade from response data is described. Solution of the inverse problem requires knowledge of the eigenproperties of the blade. The measured bending and torsional deflection data are tra

In this technical brief, we detailed how to differentiate between the part of a measurement due to a mechanical environment and the part of that measurement due to noise. We categorized noise within three broad categories: (1) acquisition; (2) instru

The data sets we have examined are real, the problems are common and the results of the experiments are diminished by subtle data acquisition errors. It should be recognized that some of the problems discussed occur simply because we tend to visually

This is but one example of how the looks of the estimated frequency response function can be deceptive. The evaluation of data requires the use of all the plots, the autospectrums of the input and the output, the coherence function and the estimated

In this technical brief, we have discussed some of the important characteristics of A/D converters that impact the quality of acquired data. Range and resolution, coupled with the appropriate gain, can minimize the effects of sampling on a data set.
