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 ...

FFT-based signal analyzers provide unprecedented modulation analysis capability and can result in much faster measurements in some cases, but much slower measurements where many FFT segments are ...

When evaluating the dynamic performance of precision ADCs using FFT analysis, coherent sampling provides the best results. In cases where coherent sampling cannot be achieved, a window function ...

For years, oscilloscopes have offered FFT functionality enabling the versatile scope to function as a basic spectrum analyzer. More recently, feature-rich spectrum-analyzer software (or, should we say ...

The traditional analysis method for spectrum features of ocean wind and wave, has the problems of the low spectrum feature definition and less total amount of data processing. In order to solve the ...
