The Zoom FFT is interesting because it blends complex down conversion, lowpass filtering, and sample rate change through decimation in a spectrum analysis application. The Zoom FFT method of spectrum ...

Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...

When evaluating the dynamic performance of precision analog-to-digital converters (ADCs) using fast Fourier transform (FFT) analysis, coherent sampling typically is used to accurately measure the ...

The last few years have shown progress in finite-element analysis intended for use by design engineers. Many programs that work with CAD provide several different types of analysis, and the range of ...

The Structural Dynamics and Acoustic Systems Laboratory (SDASL) at the University of Massachusetts Lowell was formed to address analytical and experimental problems for structural and acoustic systems ...
